(a)What is the value of the standard error of the estimate? (Round your answer to three decimal places.)

(b)Test for a significant relationship by using the t test. Use = 0.05.State the null and alternative hypotheses.

H0: 1 0 Ha: 1 = 0

H0: 1 0 Ha: 1 < 0

H0: 1 = 0 Ha: 1 0

H0: 0 = 0 Ha: 0 0

H0: 0 0 Ha: 0 = 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 cannot 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 conclude that the relationship between x and y is significant.

(c)Use the F test to test for a significant relationship. Use = 0.05.State the null and alternative hypotheses.

H0: 1 0 Ha: 1 < 0

H0: 1 0 Ha: 1 = 0

H0: 0 0 Ha: 0 = 0

H0: 1 = 0 Ha: 1 0

H0: 0 = 0 Ha: 0 0

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

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