The expected value of the treatment mean square for a completely randomized design experiment is given by E(MS Trt) = σ2 + m∑Ti2 / (L-1).

Let L be the number of treatments, and R be the number of replications per treatment.

According to the model, yij is the response from the jth replication of the ith treatment.

Therefore, the total number of observations is given by N = LR. Therefore, we assume the following linear model to estimate the treatment effects: yij=μ+Ti+Eij Where yij is the observed value for the jth replication in the ith treatment. μ represents the population mean.

Ti represents the effect of the ith treatment and is assumed to be a fixed effect. Eij is the error term for the jth replication of the ith treatment, and is assumed to follow a normal distribution with a mean of 0 and a variance of σ2.

We now turn to the analysis of variance for the CRD with L treatments and R replications per treatment.

The total sum of squares is given by: SST = ∑∑yij2 - (T..)2/N Where T.. is the total sum of observations.

It has (L-1)(R-1) degrees of freedom.

The total mean square is given by: MST = SST / (L-1)(R-1)

The treatment sum of squares is given by: SSTR = ∑n(T.)2/R - (T..)2/N Where T. is the sum of the observations in the ith treatment, and n is the number of observations in the ith treatment.

It has L-1 degrees of freedom. The treatment mean square is given by: MSTR = SSTR / (L-1)

The error sum of squares is given by: SSE = SST - SSTR It has (L-1)(R-1) degrees of freedom.

The error mean square is given by: MSE = SSE / (L-1)(R-1)

Therefore, E(MS Trt)=σ2+ m∑Ti2/t-1  since E(Ti)=0 for all i.

To show that E(MS Trt) = σ2 + m∑Ti2 / t-1

We start by using the definition of expected value E() to derive the expected value of the treatment mean square

(MS Trt): E(MS Trt) = E(SSTR / (L-1))

Next, we can express SSTR in terms of the Ti's as follows:

SSTR = ∑n(T.)2/R - (T..)2/N= 1/R ∑Ti2n - (T..)2/N

We can then substitute this expression into the expression for MS Trt:

MS Trt = SSTR / (L-1)

Substituting SSTR = 1/R ∑Ti2n - (T..)2/N, we get:

MS Trt = [1/R ∑Ti2n - (T..)2/N] / (L-1)

Simplifying the expression, we get:

MS Trt = [1/R ∑Ti2n] / (L-1) - [(T..)2/N] / (L-1)E(MS Trt)

= E([1/R ∑Ti2n] / (L-1)) - E([(T..)2/N] / (L-1))

Next, we can apply the linearity of expectation to the two terms:

E(MS Trt) = 1/(L-1) E[1/R ∑Ti2n] - 1/(L-1) E[(T..)2/N]

Simplifying the expression, we get:

E(MS Trt) = 1/(L-1) E(Ti2) - 1/(L-1) [(T..)2/N]

We note that E(Ti) = 0 for all i, since the treatments are assumed to have no effect on the population mean.

Therefore, we can simplify the expression further:

E(MS Trt) = E(Ti2) / (L-1) - [(T..)2/N] / (L-1)

Substituting the expression for Ti2 from the model, we get:

E(MS Trt) = σ2 + m∑Ti2 / (L-1)(R-1) - [(T..)2/N] / (L-1)

Simplifying the expression, we get:

E(MS Trt) = σ2 + m∑Ti2 / (L-1)

Since we have derived the expected value of MS Trt in terms of the Ti's, we can now use this result to derive E(MS Err). By definition, we have E(MS Err) = σ2.

Therefore, the expected value of the treatment mean square for a completely randomized design experiment is given by E(MS Trt) = σ2 + m∑Ti2 / (L-1). When Ti = 0 for all i, the treatments have no effect on the population mean, and hence all the observations will be independent and identically distributed with a common variance. Therefore, the experiment reduces to a randomized complete block design with one block, and the standard analysis of variance can be used to estimate the treatment effects.

The marginal propensity to consume (MPC) for Australia in 2021, when total income (Y) is 10, is 0.3.

The consumption function for Australia in 2021 is given as C = 0.0052 + 0.3Y + 20, where C represents the total consumption and Y represents the total income. To calculate the MPC, we need to determine how much of an increase in income is consumed rather than saved. In this case, when Y = 10, we substitute the value into the consumption function:

C = 0.0052 + 0.3(10) + 20

C = 0.0052 + 3 + 20

C = 23.0052

Next, we calculate the consumption when income increases by a small amount, let's say ΔY. So, when Y increases to Y + ΔY, the consumption function becomes:

C' = 0.0052 + 0.3(Y + ΔY) + 20

C' = 0.0052 + 0.3Y + 0.3ΔY + 20

To find the MPC, we subtract the initial consumption (C) from the new consumption (C') and divide it by the change in income (ΔY):

MPC = (C' - C) / ΔY

MPC = (0.0052 + 0.3Y + 0.3ΔY + 20 - 23.0052) / ΔY

Simplifying the equation, we can cancel out the terms that don't involve ΔY:

MPC = (0.3ΔY) / ΔY

MPC = 0.3

The correct rule describing the composition of Transformations is: R0,2 ∘ T0,10 ∘ R0,270°

The rule that describes the composition of transformations mapping rectangle PQRS to P''Q''R''S'', we need to analyze the given coordinates and determine the sequence of transformations.

Let's compare the coordinates of the corresponding points:

P (−3, −5) ↔ P'' (−5, 5)

Q (−2, −5) ↔ Q'' (−5, 4)

R (−2, −1) ↔ R'' (−1, 4)

S (−3, −1) ↔ S'' (−1, 5)

From the comparison, we can observe the following transformations:

1. Translation: The x-coordinate of P'' is obtained by subtracting 2 from the x-coordinate of P. The y-coordinate of P'' is obtained by adding 10 to the y-coordinate of P. This suggests a translation of (−2, 10).

2. Reflection: The x-coordinate of Q'' is obtained by reflecting the x-coordinate of Q across the y-axis. The y-coordinate of Q'' remains the same. This indicates a reflection across the y-axis.

3. Rotation: The coordinates of R'' and S'' are obtained by rotating R and S 270 degrees counterclockwise about the origin (0, 0).

Now, let's determine the composition of transformations:

The sequence of transformations that maps rectangle PQRS to P''Q''R''S'' is as follows:

1. Translation by (−2, 10)

2. Reflection across the y-axis

3. Rotation of 270 degrees counterclockwise about the origin

Therefore, the correct rule describing the composition of transformations is:R0,2 ∘ T0,10 ∘ R0,270°

Evaluating the function through differentiation, the value of f'(3) is -2/3

To find f'(3), we need to differentiate the given equation with respect to and then evaluate it at x = 3

Given:\(\(2xf(x) + \cos(f(x) - 2) = 13\)\)

Differentiating both sides with respect to x

\(\(2xf'(x) + 2f(x) + \sin(f(x) - 2) \cdot f'(x) = 0\)\)

Now, we need to substitute x = 3 and f(3) = 2 into the equation to solve for f'(3)

Plugging in x = 3 and f(3) = 2

\(\(2 \cdot 3 \cdot f'(3) + 2 \cdot 2 + \sin(2 - 2) \cdot f'(3) = 0\)\\\(6f'(3) + 4 + 0 \cdot f'(3) = 0\)\\\(6f'(3) + 4 = 0\)\)

The person is approximately 1233.35 feet from the monument

Let's call the distance from the person to the monument "x". We can use basic trigonometry to solve this problem.

From the person's point of view, the monument appears as a right triangle with the monument's height (400 feet) as the opposite side and "x" as the adjacent side. The angle of elevation (from the person to the top of the monument) is 18 degrees, which is the angle opposite the opposite side (the monument's height). So we can use the tangent function to find "x":

tan(18) = opposite / adjacent

tan(18) = 400 / x

x = 400 / tan(18)

x ≈ 1233.35 feet

To determine whether quality is associated with the source of the shipments, we need to test the competing hypotheses.

The competing hypotheses are as follows:

H0: Quality and source of shipment (vendor) are independent.
HA: Quality and source of shipment (vendor) are dependent.

To test these hypotheses, we can use a chi-square test for independence. The test statistic is calculated by comparing the observed frequencies with the expected frequencies under the assumption of independence.

b-1. To calculate the test statistic, we first need to create a contingency table with the observed frequencies of quality and source of shipment. Each cell in the table represents the count of shipments from a specific vendor with a specific quality.

For example, the table could look like this:

            | Vendor A | Vendor B | Vendor C
--------------------------------------------
Good Quality |   10     |   15     |   12
--------------------------------------------
Poor Quality |   20     |   25     |   18

Next, we calculate the expected frequencies assuming independence. The expected frequency for each cell is calculated by multiplying the row total by the column total and dividing by the total number of observations.

Finally, we calculate the chi-square test statistic by summing the squared differences between the observed and expected frequencies divided by the expected frequencies for each cell.

b-2. Once we have the test statistic, we can find the p-value associated with it. The p-value represents the probability of observing a test statistic as extreme as the one calculated, assuming the null hypothesis is true.

To find the p-value, we need to consult the chi-square table or use a statistical software. The p-value will indicate the strength of evidence against the null hypothesis. The smaller the p-value, the stronger the evidence against the null hypothesis.

Based on the given options, the p-value falls within the range of 0.01 ≤ p-value < 0.025. Therefore, we reject the null hypothesis and conclude that there is evidence to suggest that quality and source of shipment are dependent.

The town's population after 10 years is approximately 805,500

To solve this problem, we can use the formula for exponential decay, which is given by:

\(P(t) = P_{0} e^{rt}\)

where P(t) is the population at time t, P₀ is the initial population, r is the annual decay rate as a decimal, and e is the mathematical constant approximately equal to 2.71828.

In our case, the initial population P₀ is 400,000, and the annual decay rate r is 7%. We convert 7% to a decimal by dividing by 100, which gives us r = 0.07.

We want to find the population after 10 years, so we substitute t = 10 into the formula:

\(P(10) = 4,00,000e^{0.07*10}\)

Simplifying this expression, we get:

\(P(10) = 400,000e^{0.7}\)

\(e^{0.7}\) = approximately 2.01375

P(10) = 400,000 * 2.01375
