Question

b. Compare the mean of the population to the mean of the sampling distribution of the sample mean.

 

The mean of the population, ____________________, is equal to, greater to, or less to, the mean of the sample means, __________________________. (Round to two decimal places as needed.)

The assets (in billions of dollars) of the four wealthiest people in a particular country are 47, 29, 24, 17. Assume that samples of size n = 2 are randomly selected with replacement from this population of four values.

---

a. After identifying the 16 different possible samples and finding the mean of each sample, construct a table representing the sampling distribution of the sample mean. In the table, values of the sample mean that are the same have been combined.

| \(\bar{x}\) | Probability |
|-------------|-------------|
| 47          | [ ]         |
| 38          | [ ]         |
| 35.5        | [ ]         |
| 32          | [ ]         |
| 29          | [ ]         |
| 26.5        | [ ]         |
| 24          | [ ]         |
| 23          | [ ]         |
| 20.5        | [ ]         |
| 17          | [ ]         |
