Answer to Problem 16E
Relationship | Rank |
The heights of the women at age 4 and their heights at age 18. | 1 |
The heights of the father and their heights of the adult sons. | 2 |
The heights of the husband and their heights of the wives. | 3 |
Explanation of Solution
Calculation:
Consider the case rank the correlations, here three relations are given, the heights of fathers and heights of their adult sons, the heights of husband and heights of their wives, and the heights of women at age 4 and their heights at age 18. Correlation value of a variable to itself is always 1. In third case the heights of women at age 4 and their heights at age 18 will be highly correlated. In first case, the heights of fathers and heights and heights of their adult sons are related up to some extent because of heredity. But in second case the heights of husbands and heights of their wives are not related because they come from different family. Hence we can rank the correlations between these pairs of variables from highest to lowest as:
Relationship | Rank |
The heights of the women at age 4 and their heights at age 18. | 1 |
The heights of the father and their heights of the adult sons. | 2 |
The heights of the husband and their heights of the wives. | 3 |

- 2.2, 13.2-13.3) question: 5 point(s) possible ubmit test The accompanying table contains the data for the amounts (in oz) in cans of a certain soda. The cans are labeled to indicate that the contents are 20 oz of soda. Use the sign test and 0.05 significance level to test the claim that cans of this soda are filled so that the median amount is 20 oz. If the median is not 20 oz, are consumers being cheated?

- A special interest group reports a tiny margin of error (plus or minus 0.04 percent) for its online survey based on 50,000 responses. Is the margin of error legitimate? (Assume that the group’s math is correct.)arrow_forwardSuppose that 73 percent of a sample of 1,000 U.S. college students drive a used car as opposed to a new car or no car at all. Find an 80 percent confidence interval for the percentage of all U.S. college students who drive a used car.What sample size would cut this margin of error in half?arrow_forwardYou want to compare the average number of tines on the antlers of male deer in two nearby metro parks. A sample of 30 deer from the first park shows an average of 5 tines with a population standard deviation of 3. A sample of 35 deer from the second park shows an average of 6 tines with a population standard deviation of 3.2. Find a 95 percent confidence interval for the difference in average number of tines for all male deer in the two metro parks (second park minus first park).Do the parks’ deer populations differ in average size of deer antlers?arrow_forward

- Is it true that a 95 percent confidence interval means you’re 95 percent confident that the sample statistic is in the interval?arrow_forwardTines can range from 2 to upwards of 50 or more on a male deer. You want to estimate the average number of tines on the antlers of male deer in a nearby metro park. A sample of 30 deer has an average of 5 tines, with a population standard deviation of 3. Find a 95 percent confidence interval for the average number of tines for all male deer in this metro park.Find a 98 percent confidence interval for the average number of tines for all male deer in this metro park.arrow_forwardBased on a sample of 100 participants, the average weight loss the first month under a new (competing) weight-loss plan is 11.4 pounds with a population standard deviation of 5.1 pounds. The average weight loss for the first month for 100 people on the old (standard) weight-loss plan is 12.8 pounds, with population standard deviation of 4.8 pounds.
