Q:
  1. Imagine that research shows the average age of people who buy lottery tickets to be 70 with a standard deviation of 12. A sample of 30 individuals from Hawaii is selected and their ages are recorded as shown below. At a = 0.05 is there enough evidence to state that the average age of ticket buyers is the same in Hawaii as it is for the general population? (Hint: Remember to determine if this is a one-tailed or two-tailed hypothesis and perform a z test to test your hypothesis.)
