Question: 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. Problems I and II refer to the following output for a simple linear regression model:

Problems I: Referring to the displayed regression model, what percent of variation in the y variable is explained by the x variable in the model?

Problems II: Construct and interpret a 90% confidence interval estimate for the regression slope coefficient.
