Find critical value, F-test value and Test Null Hyp.Customer waiting times are studied at the Jefferson Valley Bank. When 25 randomly selected customers enter any one of several waiting lines, their times have a mean of 6.896 minutes and a standard deviation of 3.619 minutes. When 20 randomly selected customers enter a single main waiting line that feeds the individual teller stations, their waiting times have a mean of 7.460 minutes and a standard deviation of 1.841 minutes. Use a 0.05 significance level to test the claim that waiting times for the single line have a lower standard deviation. What are the critical value and F test value, each to 3 decimal places of precision? Do you reject the null hypothesis (Yes or No)? |
