Your teacher claims to produce random numbers from 1 to 5 (inclusive) on her calculator. You kept track of the results. In the past 80 rolls, the number "five" has come up only 8 times. You suspect that the calculator is producing fewer fives than it should. Let p = the true proportion of five's produced by the calculator. Which of the following could be used to determine the largest number of fives you could get in 80 rolls and still reject the null hypothesis at the a - 0.05 level? O p - 0.2 Z = - 1.645 (0.2) (0.8) 80 O p-0.2 -1.645 0.2) (0.8) 80 O D-02 -1.960 10.2108 80 O p- 0.2 -2.576 0.2)(0.8 80 O 2 - - 2.576 0 21 0.8) 80
