A leasing firm claims that the mean number of miles driven annually, u, in its leased cars is less than 13,420 miles. A random sample of 42 cars leased from this firm had a mean of 13,191 annual miles driven. It is known that the population standard deviation of the number of miles driven in cars from this firm is 3460 miles. Assume that the population is normally distributed. Is there support for the firm's claim at the 0.05 level of significance? Perform a one-tailed test. Then complete the parts below.

he manager of a computer retails store is concerned that his suppliers have been giving him laptop computers with lower than average quality. His research shows that replacement times for the model laptop of concern are normally distributed with a mean of 3.1 years and a standard deviation of 0.6 years. He then randomly selects records on 36 laptops sold in the past and finds that the mean replacement time is 2.9 years.Assuming that the laptop replacement times have a mean of 3.1 years and a standard deviation of 0.6 years, find the probability that 36 randomly selected laptops will have a mean replacement time of 2.9 years or less. P(M < 2.9 years) = Incorrect Enter your answer as a number accurate to 4 decimal places. NOTE: Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
The breaking strengths of cables produced by a certain manufacturer have a mean, u, of 1875 pounds, and a standard deviation of 100 pounds. It is claimed that an improvement in the manufacturing process has increased the mean breaking strength. To evaluate this claim, 50 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1912 pounds. Can we support, at the 0.1 level of significance, the claim that the mean breaking strength has increased? (Assume that the standard deviation has not changed.) Perform a one-tailed test.
