1. Calculate the following:

Given a population mean age of 35, with an unknown population standard deviation, what is the z score for a sample of 225 people with a mean age of 37 and a standard deviation of 10?

Given the z score you just calculated, what is the probability that you would randomly select a sample of 225 people from this population with a mean age of 37 or greater? Report as a percentage and round to no less than 2 decimals.

If I told you that I selected a sample of 225 people from this population and the mean age of that sample translated into a z score of 1.3, what is the average age of the sample?
