We wish to look at the relationship between y and x. Summary measures are given below:
n=5, SSxx=137.2, SSyy=242.8, and SSxy=-169.4
Find the t test statistic for the hypothesis H0: β1=0 vs Ha: β1≠0.
Please give detailed explanation
Solution:
Given:
n=5, SSxx=137.2, SSyy=242.8, and SSxy=-169.4
We have to find t test statistic: for the hypothesis H0: β1=0 vs Ha: β1≠0.
where
Thus
Thus
Thus t test statistic is:
