Billy wаnts tо test whether the аverаge speed оf his favоrite pitcher's fastball differs from the league average of 92 miles per hour. He takes a sample of 36 of the pitcher's fastballs and computes a sample mean of 94 miles per hour. Assume that the standard deviation of the population is 4 miles per hour. At the 5% significance level, can you conclude that Billy's favorite pitcher's fastball differs in speed from the league average? Step 1: Specify the null and alternative hypotheses (you must enter the parameters or no credit will be given for the hypotheses -- you can use the equation editor to insert symbols and Greek letters): Step 2. Find the value of the z test statistic. (Round your answer to 2 decimal places.) Step 3. Specify if the test is one-tailed or two-tailed. A) One-Tailed Test B) Two-Tailed Test Step 4. Determine the decision rule. You may use either critical value or p-value. Step 5. Determine the decision. Step 6. What is the conclusion in the language of the problem?
