    The data from exercise 1 follow.

    xi 1 2 3 4 5

    yi 3 7 5 11 14

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

    (Formula is given in the attachment).

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

    (Formula is given in the attachment).

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

    (Formula is given in the attachment).

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

    (Formula is given in the attachment).

    The attached discusses confidence intervals.
