In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student'st table, use the closest d.. that issmaller. 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.Is fishing better from a boat or from the shore? Pyramid Lake is located on the Paiute Indian Reservation in Nevada. Presidents, movie stars, and people who just want to catchfish go to Pyramid Lake for really large cutthroat trout.

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…

Another measure of central tendency that is rarely used but is easy to calculate is the midrange. It can be found using the formula below. A consumer testing service obtained the mileages (in miles per gallon) shown in the table to the right in five test runs performed with three types of compact cars. Each car manufacturer wants to advertize that its car performed the best in this test. Which of the car manufacturers of cars A, B, and C would prefer to use the midrange statistic in their ads? Explain your reasoning. Midrange= (Maximum data entry) + (Minimum data entry) 2 A 28 33 The manufacturer of (Type an integer or a decimal.) 28 29 35 Car MPG B 32 30 32 25 32 ... C 30 33 24 33 31 would prefer to use the midrange, since their car's midrange of mpg is the of the three models.
