A leasing firm claims that the mean number of miles driven annually,  μ, in its leased cars is less than 13220 miles. A random sample of 100  cars leased from this firm had a mean of 12718 annual miles driven. It is known that the population standard deviation of the number of miles driven in cars from this firm is 3480miles. Is there support for the firm's claim at the 0.05level of significance? Perform a one-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places, and round your responses as specified in the table. (If necessary, consult a list of formulas.) The null hypothesis: H0:   The alternative hypothesis: H1:   The type of test statistic: (Chooseone) Z t Chi square F             The value of the test statistic: (Round to at least three decimal places.)   The critical value at the  0.05  level of significance: (Round to at least three decimal places.)   Can we support the leasing firm's claim that the mean number of miles driven annually is less than 13220 miles?
