You are interested in finding a 90% 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. 0 9 8 1 7 9 1 11 5 1 12 b. With 90% confidence the population meannumber 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 mean number of missed class days.
