11-12. (Tw Zoe is testing to see if there is a relationship between height in feet (X) and the number of good friends (Y). The regression line for the data is Y-hat = 17.625-0.9375X. Please do a t-test for the slope of the regression line. The sample size is 5. The mean of X is 6 with a SD of 2, and the mean of Y is 12 with a SD of 9. The standard error of the equations is 10.16. (It is larger than the standard deviation of Y due to estimating with such a small sample.) You must show all your work. You will need to state the critical value and come to a conclusion about the relationship between height and the number of good friends.
