What factors affect how well a sample mean estimates a population mean? A. The scale of measurement (N.O.I.R.) and the method used to randomly assign subjects to levels of the independent variable. B. Sample size and sampling method used to select subjects from the population. C. The size of the sample standard deviation and how wide or narrow the histogram for the data is. D. All of the above

When we estimate a population mean by using the sample mean, why does increasing the sample size, n, result in a smaller sampling error? a. The above statement is incorrect; the sample size has no effect on the sampling error. b. The larger the sample size, the more closely the possible values of x̄ cluster around the mean of x̄. c. If the sample size is larger, the possible values of x̄ are farther from the mean of x. d. None of the above.

Which set of sample characteristics is most likely to produce a statistically significant value for the independent-samples t statistic? A) A small mean difference between groups and small sample variances within groups B) A large mean difference between groups and small sample variances within groups C) A large mean difference within groups and small sample variances between groups D) A small mean difference within groups and large sample variances between groups
A variable of a population is normally distributed with mean $\mu$ and standard deviation $\sigma$ a. Identify the distribution of $\bar{x}$ b. Does your answer to part (a) depend on the sample size? Explain your answer. c. Identify the mean and the standard deviation of $\bar{x}$. d. Does your answer to part (c) depend on the assumption that the variable under consideration is normally distributed? Why or why not?
