Chapter 10.5, Problem 144E
In Exercises 10.143-10.148, hypothesis tests proposed. For each hypothesis test.
- a. Identify the variable.
- b. identify the two populations.
- c. Identify the pairs.
- d. identify the paired-difference variable.
- e. determine the null and alternative hypotheses.
- f. classify the hypothesis test as two tailed, left tailed, or right tailed.
10.144 Self-Reported Weight. The article “Accuracy of Self-Reported Height and Weight in a Community-Based Sample of Older African Americans and Whites” (Journal of Gerontology Series A: Biological Sciences and Medical Sciences, Vol. 65A, No. 10, pp. 1123-1129) by G. Fillenbaum et al. explores the relationship between measured and self-reported height and weight. The authors sampled African American and White women and men older than 70 years of age. A hypothesis test is to be performed to decide whether, on average, self-reported weight is less than measured weight for the aforementioned age group.

The parameters of the approximate sampling distribution depend on the mean and variance of the underlying random variables (i.e., the population mean and variance).
