Question
Consider the data. x i 2 6 9 13 20 y i 6 19 7 27 24 (a)What is the value of the standard error
Consider the data.
xi | 2 | 6 | 9 | 13 | 20 |
|---|---|---|---|---|---|
yi | 6 | 19 | 7 | 27 | 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 thettest. Use= 0.05.State the null and alternative hypotheses.
H0:1= 0 Ha:10H0:0= 0 Ha:00 H0:10 Ha:1< 0H0:10 Ha:1= 0H0:00 Ha:0= 0
Find the value of the test statistic. (Round your answer to three decimal places.)Find thep-value. (Round your answer to four decimal places.)p-value = State your conclusion.
