\fYou 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 15 randomly selected college students. Round answers to 3 decimal places where possible. 3 11 11 4 3 10 10 10 4 12 8 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 15 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 Hint: Hints D Video [+] Submit Question\fThe IQ scores of 50 students are given below. 107 110 85 00 96 16 08 85 111 107 92 94 88 100 90 90 12 107 1 12 100 98 86 115 86 89 94 105 90 02 07 11- 04 17 08 108 86 100 103 17 100 111 85 112 105 92 86 118 88 118 110 (a) Construct a grouped frequency distribution for the data.
