69. The following table gives the number of fatal accidents of U.S. commercial airline carriers in the 16 years from 1980 to 1995. Do these data disprove, at the 5 percent level of significance, the hypothesis that the mean number of accidents in a year is greater than or equal to 4.5? What is the p-value? (Hint: First formulate a model for the number of accidents.)
