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 10 randomly selected college students. Round answers to 3 decimal places where possible. 8 11 11 5 6 8 | 3 | 7 | 9|4| 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 10 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.

**Title: Calculating a 95% Confidence Interval for Class Absences** 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 10 randomly selected college students. Round answers to 3 decimal places where possible. Data: - 8, 11, 11, 5, 6, 8, 3, 7, 9, 4 **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 10 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.
