Test the claim thatthe standard deviation of waiting times is less than 2.3 minutes, which is the standard deviation of waiting times at the same bank when separate waiting linesare used at each teller window. Use a significance level of 0.05. Assume that the sample is a simple random sample selected from a normally distributedpopulation. Complete parts (a) through (d) below.Click on the icon to view the data.b. Compute the test statistic.(Round to two decimal places as needed.)c. Find the P-value of the test statistic.CThe P-value of the test statistic is(Round to three decimal places as needed.)d. Does the use of the single line appear to reduce the variation among waiting times?

The data shows the waiting times of customers at a bank.
