The annual salary for one particular occupation is normally distributed, with a mean of about $137,000 and a standard deviation of about $25,000. Random samples of 42 are drawn from this population, and the mean of each sample is determined. Find the mean and standard deviation of the sampling distribution of thesesample means. Then, sketch a graph of the sampling distribution.The mean is µ; = |, and the standard deviation is o; =(Round to the nearest integer as needed.

A political newspaper, Politically Sound, is interested in the distances voters in Rising Falls County live from their nearest polling station. Politically Sound has hired you to estimate the population mean of all such distances for voters in this county. To estimate this population mean, you select a random sample of 17 Rising Falls County voters and record the distance (in km) each voter lives from their nearest polling station. Assume the population is approximately normally distributed. Based on your sample, follow the steps below to construct a 99% confidence interval for the population mean of all the distances voters in Rising Falls County live from their nearest polling station. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results for your random sample.
