You may need to use the appropriate technology to answer this question.Consider the data.
xi | 2 | 6 | 9 | 13 | 20 |
---|---|---|---|---|---|
yi | 8 | 18 | 8 | 25 | 24 |
(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 =
What is your conclusion?
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.
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.
