Question

10.15 A psychologist theorized that people can hear better when the have just eaten a large meal. Six individuals were randomly assigned to eat either a large meal or a small meal. After eating the meal, their hearing was tested. The hearing ability scores (high numbers indicate greater ability) are given below. Using the 0.05 level, do the results support the psychologist’s theory

Answer 1

H0 is u = u1
H1 is u not equal to u2

But you have not specified the results of the test to check the hypothesis with!?!

Answer 2

This experiment (as you state it) is faulty. You need to test hearing <B>before</B> and after eating to note the effect of the meals on hearing.

Also the scores are not given. For most, copy and paste does not work.
