The exercises arc based on the following sample data obtained from different second-year medical students who took blood pressure measurements of the same person (based on data from Marc Triola, MD).

Systolic	138	130	135	140	120
Diastolic	82	91	100	100	80

1. If you plan to use a 0.05 significance level in a test of a correlation between the systolic and diastolic readings, what are the critical values of r?

Expert Solution & Answer

To determine

To find: The critical values of r.

Answer to Problem 1CQQ

The critical value of r is±0.878.

Explanation of Solution

Given info:

The data shows that the measurements of systolic and diastolic blood pressures. The level of significance is α=0.05 .

Calculation:

Critical value:

The degrees of freedom (n) is 5. From the TABLE A-6 “Critical Values of the Pearson Correlation Coefficient r”, the critical value for 5 degrees of freedom and α=0.05 level of significance is ±0.878.

Conclusion:

Thus, the critical value of r is±0.878.

You are planning an experiment to determine the effect of the brand of gasoline and the weight of a car on gas mileage measured in miles per gallon. You will use a single test car, adding weights so that its total weight is 3000, 3500, or 4000 pounds. The car will drive on a test track at each weight using each of Amoco, Marathon, and Speedway gasoline. Which is the best way to organize the study? Start with 3000 pounds and Amoco and run the car on the test track. Then do 3500 and 4000 pounds. Change to Marathon and go through the three weights in order. Then change to Speedway and do the three weights in order once more. Start with 3000 pounds and Amoco and run the car on the test track. Then change to Marathon and then to Speedway without changing the weight. Then add weights to get 3500 pounds and go through the three gasolines in the same order.Then change to 4000 pounds and do the three gasolines in order again. Choose a gasoline at random, and run the car with this gasoline at…
