(2) A state executive claims that the average cost of tuition at public colleges is $5700. A researcher wishes to test the claim that this cost is greater than $5700. She selects a random sample of 36 public colleges and finds the mean to be $5950.The population standard deviation is $659. Is there enough evidence to support the claim that the cost of tuition is greater than $5700 at a 0.05?

In a random sample of 13 microwave ovens, the mean repair cost was $90.00 and the standard deviation was $15.30. Using the standard normal distribution with the appropriate calculations for a standard deviation that is known, assume the population is normally distributed, find the margin of error and construct a 98% confidence interval for the population mean. A 98% confidence interval using the t-distribution was (78.6, 101.4). Compare the results.
