You are interested in finding a 98% confidence interval for the mean number of visits for physical therapy patients. The data below show the number of visits for 10 randomly selected physical therapy patients. Round answers to 3 decimal places where possible 13 10 23 19 9 11 13 21 7 distribution a. To compute the confidence interval use a b. With 98% confidence the population mean number of visits per physical therapy patient is between 10 visits * and 3 c. If many groups of 10 randomly selected physical therapy patients are studied, 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 visits per patient and about |* percent will not contain the true population mean number of visits per patient You want to obtain a sample to estimate a population proportion. Based on previous evidence, you believe the population proportion is approximately p 0.28. You would like to be 90% confident that your esimate is within 4% of the true population proportion.

distribution
a. To compute the confidence interval use a
b. With 98% confidence the population mean number of visits per physical therapy
patient is between 10
visits
* and
3
c. If many groups of 10 randomly selected physical therapy patients are studied, 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
visits per patient and about
|* percent will not contain the true population
mean number of visits per patient

You want to obtain a sample to estimate a population proportion. Based on previous
evidence, you believe the population proportion is approximately p 0.28. You
would like to be 90% confident that your esimate is within 4% of the true population
proportion. How large of a sample size is required?
