To determine the solution to problem 5, you will need to:

calculate the mean of all the park acreages (the population mean)

select a random sample of 20 of the values

calculate the sample mean,

construct a 90% confidence interval around that sample mean

determine whether the population mean can be found within your confidence interval

Problem #5: From Data Set VI in Appendix B, select a sample of 20 values and find the 90% confidence interval of the mean of the number of acres. Find the mean of all the values, and determine if the confidence interval contains the mean.

Is the population mean contained in the confidence interval? Be sure to justify your explanation.
