You are interested in finding a 95% confidence interval for the mean number of visits for physical therapy patients. The data below show the number of visits for 13 randomly selected physical therapy patients. 11,8,12,9,7,12,10,9,8,4,16,9,7, Assume a normal distribution and round your answers to two decimal places. A. The sampling distribution follows a  distribution. B. With 95% confidence, the mean number of visits per physical therapy patient is   between and visits. C. If many groups of 13 randomly selected physical therapy patients 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 the number of visits per patient and about percent will not contain the true population mean a number of visits per patient.

Question

You are interested in finding a 95% confidence interval for the mean number of visits for physical therapy patients. The data below show the number of visits for 13 randomly selected physical therapy patients.

11,8,12,9,7,12,10,9,8,4,16,9,7,

Assume a normal distribution and round your answers to two decimal places.

A. The sampling distribution follows a  distribution.

B. With 95% confidence, the mean number of visits per physical therapy patient is

 

between and visits.

C. If many groups of 13 randomly selected physical therapy patients 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 the number of visits per patient and about percent will not contain the true population mean a number of visits per patient.
