Question: Consider the data. x i 1 2 3 4 5 y i 4 6 5 12 13 (a) Compute the mean square error using equation

Consider the data.

xi

1 2 3 4 5

yi

4 6 5 12 13

(a)

Compute the mean square error using equation s2 = MSE =

SSE
n 2

. (Round your answer to two decimal places.)

(b)

Compute the standard error of the estimate using equation s =

MSE

=

SSE
n 2

. (Round your answer to three decimal places.)

(c)

Compute the estimated standard deviation of

b1

using equation sb1 =

s
(xi x)2

. (Round your answer to three decimal places.)

(d)

Use the t test to test the following hypotheses ( = 0.05):

H0: 1 = 0
Ha: 1 0

Find the value of the test statistic. (Round your answer to three decimal places.)

Find the p-value. (Round your answer to four decimal places.)

p-value =

State your conclusion.

Do not reject H0. We conclude that the relationship between x and y is significant.Reject H0. We conclude that the relationship between x and y is significant. Do not reject H0. We cannot conclude that the relationship between x and y is significant.Reject H0. We cannot conclude that the relationship between x and y is significant.

(e)

Use the F test to test the hypotheses in part (d) at a 0.05 level of significance. Present the results in the analysis of variance table format.

Set up the ANOVA table. (Round your values for MSE and F to two decimal places, and your p-value to three decimal places.)
