Problem 2 (8.9 modified)
A study of the average salaries of New York City residents was
conducted for 770 different jobs. It was found that massage
therapists average $58,260 in yearly income. Suppose the study
surveyed 25 massage therapists and had a standard deviation of
$3,250. Perform a significance test of the null hypothesis that the
average massage therapist makes $55,000 per year against the
one-sided alternative that it is more. Assume the data is normally
distributed.
Next, suppose the true population mean is $57,000. Find beta, the probability of type II error.
