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 (ux) with the mean time (in minutes) of college students to write an error-free program (µy). Data taken from two independent samples were summarized as follows: Statistics High school College Mean time 70 84 Standard deviation Sample size 10 12 10 10 Assuming normality of both populations, compute a 90% confidence interval estimate for µx
