You are given the following sample data:
x y
10…………………...3
6………………….....7
9………………….....3
3………………….....8
2………………….....9
8………………….....5
3………………….....7
a. Develop a scatter plot for these data.
b. Determine the regression equation for the data.
c. Develop a 95% confidence interval estimate for the true regression slope and interpret this interval estimate.
d. Provide a 95% prediction interval estimate for a particular y, given xp = 7.
