Repeat parts (b)–(e) of Exercise 7.17 for samples of size 4. (There are 15 possible samples.)

b. For samples of size 2, construct a table similar to Table 7.2. (There are 15 possible samples of size 2.)

c. Draw a dotplot for the sampling distribution of the sample mean for samples of size 2.

d. For a random sample of size 2, what is the chance that the sample mean will equal the population mean?

e. For a random sample of size 2, determine the probability that the mean wealth of the two people obtained will be within 2 (i.e., $2 billion) of the population mean. Interpret your result in terms of percentages.

## Answer to relevant Questions

Repeat parts (b)–(e) of Exercise 7.17 for samples of size 5. (There are six possible samples.) b. For samples of size 2, construct a table similar to Table 7.2. (There are 15 possible samples of size 2.) c. Draw a dotplot ...In this section, we stated that, when the sample size is small relative to the population size, there is little difference between sampling with and without replacement. Explain in your own words why that statement is true. Refer to Exercise 7.9 on page 284. Population data: 1, 2, 3, 4, 5, 6. a. Use your answers from Exercise 7.9(b) to determine the mean, μx-bar, of the variable x-bar for each of the possible sample sizes. b. For each of the ...According to the Bureau of Labor Statistics publication News, self-employed persons with home-based businesses work a mean of 25.4 hours per week at home. Assume a standard deviation of 10 hours. a. Identify the population ...A statistic is said to be an unbiased estimator of a parameter if the mean of all its possible values equals the parameter; otherwise, it is said to be a biased estimator. An unbiased estimator yields, on average, the ...Post your question
