A fitness center is interested in finding a 95% confidence interval for the mean number of days per week that Americans who are members of a fitness club go to their fitness center. Records of 238 members were looked at and their mean number of visits per week was 3.1 and the standard deviation was 2.8. Round answers to 3 decimal places where possible. a. With 95% confidence the population mean number of visits per week is between and visits. b. If many groups of 238 randomly selected members 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 week and about percent will not contain the true population mean number of visits per week.

A fitness center is interested in finding a 90% confidence interval for the mean number of days per week that Americans who are members of a fitness club go to their fitness center. Records of 225 members were looked at and their mean number of visits per week was 2.1 and the standard deviation was 1.9. Round answers to 3 decimal places where possible. a. With 90% confidence the population mean number of visits per week is between and visits. b. If many groups of 225 randomly selected members 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 week and about percent will not contain the true population mean number of visits per week.
How much money does the average professional hockey fan spend on food at a single hockey game? That question was posed to 10 randomly selected hockey fans. The sampled results show that sample mean and standard deviation were $12.00 and $2.80, respectively. Use this information to create a 95% confidence interval for the mean. Express the answer in the form x+ t/2 (s/ Vn). O A. 12+ 1.833(2.80//10) O B. 12+2.262(2.80//10 OC. 12+2.228(2.80//10) O D. 12+2.201(2.80//10)
