A random sample 33 salaries yields an average of $54536.16. Use a = 0.01, and assume that o = $1400. 1. The sample size restriction for this test is: O Need at least 5 successes and 5 failures O Need n > 30 O None needed since population is normally distributed e The hypotheses are: О Но:р — 54000; На:р + 54000 O Ho:p 54000 O Ho:p > 54000; Ha:p 54000 or O Ho:µ > 54000; Ha: µ < 54000 2.
