You are interested in finding a 99% confidence interval for the mean number of visits for physical therapy patients. The data below show the number of visits for 12 randomly selected physical therapy patients. Round answers to 3 decimal places where possible. 13 11 11 19 19 27 22 23 7 22 26 28 a. To compute the confidence interval use a ? z t distribution. b. With 99% confidence the population mean number of visits per physical therapy patient is between and visits. c. If many groups of 12 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 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 11 randomly selected college students. Round answers to 3 decimal places where possible. 1 98 05 4 2 8 4 11 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 11 randomly selected non-residential college students are surveyed, then a different confidence interval would be produced from each group.

In a survey of 2295 adults, 746 say they believe in UFOs. Construct a 90% confidence interval for the population proportion of adults who believe in UFOs. A 90% confidence interval for the population proportion is (nothing,nothing). (Round to three decimal places as needed.) Interpret your results. Choose the correct answer below. A. With 90% confidence, it can be said that the sample proportion of adults who believe in UFOs is between the endpoints of the given confidence interval. B. The endpoints of the given confidence interval shows that 90% of adults believe in UFOs. C. With 90% confidence, it can be said that the population proportion of adults who believe in UFOs is between the endpoints of the given confidence interval. D. With 90% probability, the population proportion of adults who do not believe in UFOs is between the endpoints of the given confidence interval.
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 11 randomly selected physical therapy patients. Round answers to 3 decimal places where possible. 27 5 28 22 15 9 16 10 25 18 5 a. To compute the confidence interval use a Z OR T distribution. b. With 98% confidence the population mean number of visits per physical therapy patient is between ? and ? visits. c.
