7. A car dealership would like to estimate the mean mpg of
its new model car with 90% confidence. The population is normally
distributed; however we are taking a sample of 25 cars with a
sample mean of 96.52 and a sample standard deviation of 10.70.
Calculate a 90% confidence interval for the population mean using
this sample data.
