Heights and Gender It is a well-accepted fact that males are taller on the average than females. But how much taller? The genders of 105 biomedical students were also recorded and the data are summarized below: Males Females Sample Size 48 77 Sample Mean 69.58 64.43 Sample 2.62 2.58 Standard Deviation a. Perform a test of hypothesis to either confirm or refute our initial claim that males are taller on the average than females? Use a = .01. b. If the results of part a show that our claim was correct, construct a 99% confidence one- sided lower confidence bound for the average difference in heights between male and female college students. How much taller are males than females?

Autopitch devices are made for both major- and minor-league teams to help them improve their batting averages. When set at the standard position, Autopitch can throw hardballs toward a batter at an average speed of 53 mph. To monitor these devices and to maintain the highest quality, Autopitch executive Neil Geismar takes samples of 9 devices at a time. The average range is 4 mph. a) Using this information, construct control limits for the x-chart. UCL,-mph (round your response to three decimal places).
