Refer to the data set in the accompanying table. Assume that the paired sample data is a simple random sample and the differences have a distribution that is approximately normal. Use a significance level of 0.10 to test for a difference between the weights of discarded paper (in pounds) and weights of discarded plastic (in pounds). Click the icon to view the data In this example, Hg is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the weight of discarded paper minus the weight of discarded plastic for a household.

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).

Use z scores to compare the given values. The tallest living man at one time had a height of 239 cm. The shortest living man at that time had a height of 133.8 cm. Heights of men at that time had a mean of 174.58 cm and a standard deviation of 6.12 cm. Which of these two men had the height that was more extreme? Question content area bottom Part 1 Since the z score for the tallest man is z=enter your response here and the z score for the shortest man is z=enter your response here, the ▼ shortest tallest man had the height that was more extreme.
