Come up with a unique example of something that could be tested with a single-sample z-test and conduct the confidence interval and effect size calculations. Be creative!

a) Provide your example scenario for a single-sample z-test that includes the population mean, population standard deviation, sample size, and sample mean. Do not only present the numbers; you need a reasonable example of something that could be tested with a single-sample z-test.

b) Explain why your example is appropriate for a single-sample z-test.

c) Calculate both the 99% confidence interval and effect size for your example, showing your work for each.
