The following data represent the relationship between the number of alignment errors and the number of missing rivets for 10 different aircraft. Number of Number of Missing Rivets = x Alignment Errors = y 13 7 15 7 10 5 22 12 30 15 7 2 25 13 16 9 20 11 15 8 (a) Plot a scatter diagram. (b) Estimate the regression coefficients. (c) Test the hypothesis that = 1. (d) Estimate the expected number of alignment errors of a plane having 24 missing rivets. (e) Compute a 90 percent confidence interval estimate for the quantity in (d).
