1. A simple random sample of 35 has a mean of 44.3 miles and a standard deviation of 2.0 miles. Which of the following is a 99% confidence interval estimate for the population mean? a. (43.637,44.963) b. (43.429 , 45.171) c. (43.378 , 45.222) d. (43.613 , 44.987) We will take 200 simple random samples, each of size 50, from the given population and calculate the 90% confidence interval for μ for each. Approximately how many 200 intervals will contain...

Problem Page The human resources department of a consulting firm gives a standard creativity test to a randomly selected group of new hires every year. This year, 70 new hires took the test and scored a mean of 113.1 points with a standard deviation of 14. Last year, 85 new hires took the test and scored a mean of 116.9 points with a standard deviation of 15.3. Assume that the population standard deviations of the test scores of all new...
