Please see problem A leasing rm claims that the mean number ofmiles driven annually, p, in its leased cars is less than 12780

A leasing rm claims that the mean number of miles driven annually, p, in its leased cars is less than 12780 miles. A random sample of 60 cars leased from this rm had a mean of 12153 annual miles driven. It is known that the population standard deviation of the number of miles driven in cars from this rm is 1780 miles. Is there support for the firm's claim at the 0.01 level of significance? Perform a one-tailed test. Then ll in the table below. Carry your intermediate computations to at least three decimal places, and round your responses as specied in the table. (If necessary, consult a list of formulas.) The null hypoth_esis: H0 : I] 1-1 O P _ A x 5 P The alternative hum: H1 : I] = The type of test statistic: (Choose one) C D B [La ELI] EIEI EIEl The value of the test statistic: (Round to at least three D decimal places.) X s ? The critical value at the 0.01 level of signicance: '1 (Round to at least three decimal places.) Fi] E ME Can we support the leasing firm's claim that the mean number of miles driven annually is less than 12780 miles
