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. In the following data pairs, A represents the cost of living index for utilities and B represents the cost of living index for transportation. The data are paired by metropolitan areas in the United States. A random sample of 46 metropolitan areas gave the following information. Do the data indicate that the U.S. population mean cost of living index for utilities is less than that for transportation in these areas? Use α = 0.05. (Let d = A − B.) (a) What is the level of significance? (b)What is the value of the sample test statistic? (Round your answer to three decimal places.)
Which of the following is not an aspect involved in computing the sum of products ( SP) of deviations? a. dividing by the total number of participants b. subtracting the total sum of squares collapsed across all scores c. adding the total X and Y scores across all participants d. multiplying the X and Y scores together for each participant
Which of the following is an example of doing inferential statistics? You calculate the average grade on an exam in a class of 5th grade math students to see if they did better or worse than last year. You lookup the median and the standard deviation of the age for the U.S. population from U.S. Census data. You use a sample of homes in Rancho Cucamonga to draw a conclusion about the mean home price for all Rancho Cucamonga homes. You compare the distributions of scores for two Social Science 10 classes to see which class did better on the exam.

See picture for questions a and b. Problem For admission to graduate school, Diane is taking the physics subject-matter test, and Lena is taking the chemistry subject-matter test. For each of these tests, the distribution of scores is clearly bell-shaped. Scores for the physics test have a population mean of 631 points with a standard deviation of 26 points. Scores for the chemistry test have a population mean of 608 points with a standard deviation of 35 points. Diane scored 695 on the physics test, and Lena scored 667 on the chemistry test.
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. In environmental studies, sex ratios are of great importance. Wolf society, packs, and ecology have been studied extensively at different locations in the U.S. and foreign countries.
