# Question

The following are the amounts of money (in dollars) spent by 16 persons at an amusement park: 20.15, 19.85, 23.75, 18.63, 21.09, 25.63, 16.65, 19.27, 18.80, 21.45, 20.29, 19.51, 23.80, 20.00, 17.48, and 19.11. Assuming that this is a random sample from a symmetrical population and that the probability that a person will spend exactly $ 19.00 is extremely small, use the sign test at the 0.05 level of significance to test the null hypothesis that on the average a person spends $ 19.00 at the park against the alternative hypothesis that this figure is too low. Base the test on Table I.
