Hypothesis Test For the sample data from Exercise 1, we have s = 0.5 and we want to use that sample to test the claim that the sample is from a population with a standard deviation less than 1.8 min (as it was in the past with multiple waiting lines). a. Identify the null and alternative hypotheses. b. Find the value of the test statistic. c. Using technology, the P -value is found to be 0.0001. What should we conclude about the null hypothesis? d. Given that the P -value is 0.0001, what should we conclude about the original claim? e. What does the conclusion suggest about the effectiveness of the change from multiple waiting lines to a single line?
