Question 1 1. For the following data: 22, 25, 26, 27, 27, 29, 30, 36, 36, 44. Determine the frequency and plot the column bar. • Calculate the average, standard deviation, mode, median.
In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer. The western United States has a number of four-lane interstate highways that cut through long tracts of wilderness. To prevent car accidents with wild animals, the highways are bordered on both sides with 12-foot-high woven wire fences. Although the fences prevent accidents, they also disturb the winter migration pattern of many animals. To compensate for this disturbance, the highways have frequent wilderness underpasses designed for exclusive use by deer, elk, and other animals. In Colorado, there is a large group of deer that spend their summer months in a region on one side of a highway and survive the winter months in a lower region on the other side. To…

2. You need to present data to your boss and an assistant gives you a scatter gram with random points. They do not seem to form a line but r = 0.95. You did not draw the graph or calculate r. You do have the original data in front of you and it is accurate. How would you handle the discrepancy between the scatter gram and value for r?
