Question:

The data from exercise 1 follow.

1 2 3 4 y; 3 7 5 11 14

a. Use equation (14.23) to estimate the standard deviation of yˆ* when x = 4.

b. Use expression (14.24) to develop a 95% confidence interval for the expected value of y when x = 4.

c. Use equation (14.26) to estimate the standard deviation of an individual value of y when x = 4.

d. Use expression (14.27) to develop a 95% prediction interval for y when x = 4.
