Use the formula of Exercise 14.29 to calculate a 95% confidence interval for β for the numbers of hours studied and the test scores on page 388 and compare this interval with the one obtained in Example 14.6. If the row categories as well as the column categories of an r × c table are ordered, we can replace the row headings and also the column headings by consecutive integers and then calculate r with the formula obtained in ...When the x1’s, x2’s, . . . , and/or the xk’s are equally spaced, the calculation of the β^’s can be simplified by using the coding suggested in Exercise 14.15. Rework Exercise 14.80 coding the x1-values – 1, 0, ...Prove the statement made on page 436; that Prove Theorem 15.2.
