One hundred draws are made at random with replacement from a box of tickets; each ticket has a number written on it. The average of the draws is 29 and the SD of the draws is 40. You see a statistician make the following calculation:
z = 29 - 20/4 = 2.25, P ~ 1%
a. She seems to be testing the null hypothesis that the average of the is 20. Options; box, sample.
b. True or false: there is about a 1 % chance for the null hypothesis to be right. Explain briefly.
