A leasing firm claims that the mean number of miles driven annually, in its leased cars is less than 12380 miles. A random sample of 70 cars leased from this firm had a mean of 11552 annual miles driven. It is known that the population standard deviation of the number of miles driven in cars from this firm is 2580 miles. Is there support for the firm's claim at the 0.01 level of significance? Perform a one-tailed test. Then fill...
