A study is conducted between high school students and college students to compare their proficiency at writing computer programs for microcomputers. For this study, the researchers wish to compare the mean time (in minutes) of high school students to write an error-free program (x) with the mean time (in minutes) of college students to write an error-free program (uy). Assuming normality of both populations, compute a 90% confidence interval estimate for (μx - μy). Data taken from two independent samples were summarized as follows: Statistics High School College 84 Mean time 70 Standard deviation 10 12 Sample size 10 10
