A survey by the Southern Company found that families spend

Question A survey by the Southern Company found that families spend on average $165.25 for power to run their house each month. Assume the standard deviation is $30.55. Find the percentage of families who spend less than $200.00 a month. Assume the variable is normally distributed.

It has been hypothesized that, on average, employees spend one

Question It has been hypothesized that, on average, employees spend one hour a day playing video games at work. To test this at her company, a manager takes a random sample of 35 employees, who showed a mean time of 55 minutes per day, with an assumed population standard deviation of 5 minutes.1.     Calculate the test statistic 2.     What is the critical value for testing these hypotheses at α = .01?3.     Calculate a confidence interval to test the hypotheses that the employees spend a different amount of time from one hour (60 minutes) at α = .01 and interpret.
