A leasing firm claims that the mean number of miles driven annually, μ, in its leased cars is less than 13,700 miles. A random sample of 70 firm had a mean of 13,689 annual miles driven. It is known that the population standard deviation of the number of miles driven in cars fro miles. Is there support for the firm's claim at the 0.05 level of significance? Perform a one-tailed test.
