We will perform another test to determine whether record highs are more likely to have occurred recently. If a record high is equally likely to occur in any year of observation, the mean year in which a record is observed would occur at the midpoint of the observation period, which is (1871 + 2018)/2 =

1944.5. Use the data in Table 9.4 to test the hypothesis that the mean year in which a record high occurred is 1944.5 against the alternative that it is greater. What do you conclude?
