A random sample of size 15 from a normal distribution has standard deviation s = 74. Test H_{0} : ? = 40 versus H_{1} : ? > 40. Use the ? = 0.01 level of significance. Part 1 of 5 The hypotheses are provided above. This hypothesis test is a right-tailed test. Part 2 of 5 Find the critical value. Critical value =

Step 1
This means that we are looking for values that are greater than our hypothesized mean. Second, we are given that the level of significance (alpha) is 0.01. This is the probability of rejecting the null hypothesis when it is true. Third, we are dealing with a Show more…
