The data table contains waiting times of customers at a bank, where customers enter a single waiting line that feeds three teller windows. Test the claim that the standard deviation of waiting times is less than 1.9 minutes, which is the standard deviation of waiting times at the same bank when separate waiting lines are used at each teller window. Use a significance level of 0.025. Complete parts (a) through (d) below.a. Identify the null and alternative hypotheses. Choose the correct answer below. b. Compute the test statistic. c. Find the P-value of the test statistic. d. Does the use of the single line appear to reduce the variation among waiting times?
