Question

You are interested in finding a 98% 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.

2 | 0 | 10 | 7 | 11 | 1 | 3 | 11 | 2 | 0 |

a. To compute the confidence interval use a ? t z distribution.

b. With 98% 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.
