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).

Given the data set below find the following; 45, 34, 65, 20, 15, 25 a. Compute the sample mean b. Compute the sample standard deviation c. Compute the standard error of the mean.
1. Measure your height and find how many standard deviations you are from 50th percentile using the Anthropometry table in slide 17 in the Anthropometry slides. My height is 5 feet 7 inches. 2. Using this measured stature, estimate the lengths of your forearm, foot, and hand (https://exrx.net/Kinesiology/Segments). 3. Measure your forearm, foot, and hand using a tape measure (or some other device).( forearm= 7inches; foot=10inches; hand=22inches). 4. Indicate the error in %s for each segment (compare measured vs table value), and indicate which if your 3 segments was the furthest off.
