The temperature distribution of city D has a population mean µ= 21.3, and standard deviation o =4.8. You randomly select 12 days and get the temperature for these days. Then you compute thesample mean. What is the maximum sample mean value in the bottom 0.22 x 100% of the samplemean distribution? Note that we're talking about the distribution of the sampling mean. Give youranswer to 2 decimal places.

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. Take Sample Number of voters 17 Sample mean 4.757 Sample standard deviation 2.363 Enter the values of the sample size, the point estimate of the mean, the sample standard deviation, and the…
