8. You are thinking about buying a motel located on Interstate 64. Before you make up your mind, you want to estimate the average number of vehicles that go by the motel cach day in the summer. Fortunately, the highway department has been counting vehicles on I-64 near the motel. A random sample of 36 summer days shows an average of x= 16,000 cars per day with s = 2400 cars. Find a 90% confidence interval for the mean number of cars per summer day going past the motel. Interpret your results in context.
