10) In an analysis investigating the usefulness of pennies, cents portions of 100 randomly selected credit card charges are recorded, and they have a mean of 47.6 cents and standard deviation of 33.5 cents. If the amounts from 0 cents to 99 cents are all equally likely, the mean is expected to be 49.5 cents and population standard deviation is expected to be 28.866 cents. Use a 0.01 significance level to test the claim that the sample is from population with the standard deviation equal to 28.866 cents. Use the Critical Value Method (Traditional Method).
