2.Mosteller and Tukey (1977) reported data on verba test scores for sixth graders. They used a sample of 20 Mid-Atlantic and New England schools taken from The Coleman Report. The dependent variable y was the mean verbal test score for each school. The predictor variables were

x1 ? staff salaries per pupil,

x2 ? percent of sixth grade fathers employed in white collar jobs,

x3 ? a composite score measuring socioeconomic status,

x4 ? the mean score on a verbal test administered to teachers,

x5 ? one-half of the sixth grade mothers' mean number of years of schooling. Schools meet a performance standard set for them

(by me) if their average verbal test score is above 37. The data are given In
