The data below show the number of missed days for 10 randomly selected college students. Round answers to 3 decimal places where possible. 7 8 10 6 6 2 3 11 8 a. To compute the confidence interval use a t v distribution. b. With 90% confidence the population mean number of days of class that college students miss is between and days. c. If many groups of 10 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group. About |90 percent of these confidence intervals will contain the true population mean number of missed class days and about 10 percent will not contain the true population mean number of missed class days
