You are interested in finding a 95% confidence interval for the average number of days of class that college students miss each year. The data below show the number of missed days for 11 randomly selected college students. Round answers to 3 decimal places where possible. 7 7 7 8 2 6 9 9 4 5 7 a. To compute the confidence interval use a distribution. b. With 95% confidence the population mean number of days of class that college students miss is between___ and____ days. c. If many groups of 11 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group. About___ percent of these confidence intervals will contain the true population mean number of missed class days and about___ percent will not contain the true population
