Use the following to answer the questions below:

A small university is trying to monitor its electricity usage. For a random sample of 30 weekend days (Saturdays and Sundays), the student center used an average of 94.26 kilowatt hours (kWh) with standard deviation 43.29. For a random sample of 60 weekdays, (Monday - Friday), the student center used an average of 112.63 kWh with standard deviation 32.07.


Test, at the 5% level, if significantly more electricity is used at the student center, on average, on weekdays than weekend days. Include all details of the test.
