Question
Consider the data. x i 2 6 9 13 20 y i 9 19 11 27 23 (a)What is the value of the standard error
Consider the data.
xi | 2 | 6 | 9 | 13 | 20 |
---|---|---|---|---|---|
yi | 9 | 19 | 11 | 27 | 23 |
(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: 0 0 Ha: 0 = 0
H0: 0 = 0 Ha: 0 0
H0: 1 = 0 Ha: 1 0
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.
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.
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.(
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: 0 0 Ha: 0 = 0
H0: 1 0 Ha: 1 < 0
H0: 0 = 0 Ha: 0 0
H0: 1 = 0 Ha: 1 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 =
What is your conclusion?
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 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.
