A leasing firm claims that the mean number of miles driven annually, u, in its leased cars is less than 13560miles. A random sample of 30 cars leased from this firm had a mean of 12219 annual miles driven. It isknown that the population standard deviation of the number of miles driven in cars from this firm is 3060miles. Assume that the population is normally distributed. 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 asspecified in the table. (If necessary, consult a list of formulas.)The null hypothesis:Но:хThe alternativeНhypothesis:OSOThe type of test statistic:(Choose one)O#0ロ<ロO>OThe value of the teststatistic:(Round to at least threedecimal places.)The p-value:(Round to at least threedecimal places.)Can we support the leasing firm's claimthat the mean number of miles drivenYesNoannually is less than 13560 miles?

Condé Nast Traveler conducts an annual survey in which readers rate their favorite cruise ship. All ships are rated on a 100-point scale, with higher values indicating better service. A sample of 37 ships that carry fewer than 500 passengers resulted in an average rating of 85.35, and a sample of 43 ships that carry 500 or more passengers provided an average rating of 81.60. Assume that the population standard deviation is 4.54 for ships that carry fewer than 500 passengers and 3.99 for ships that carry 500 or more passengers. Round your all answers to two decimal places. a. What is the point estimate of the difference between the population mean rating for ships that carry fewer than 500 passengers and the population mean rating for ships that carry 500 or more passengers? b. At 95% confidence, what is the margin of error? c. What is a 95% confidence interval estimate of the difference between the population mean ratings for the two sizes of ships? to

The manager of a computer retail 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 3.9 years and a standard deviation of 0.6 years. He then randomly selects records on 47 laptops sold in the past and finds that the mean replacement time is 3.7 years. Assuming that the laptop replacement times have a mean of 3.9 years and a standard deviation of 0.6 years, find the probability that 47 randomly selected laptops will have a mean replacement time of 3.7 years or less. P(M≤ 3.7 years) - Enter your answer rounded to 4 decimal places.

Fifteen randomly selected oil wells produce an average of 30 barrels of crude oil per day with a standard deviation of 3.5 barrels. Is there enough evidence to conclude that the oil wells are not producing an average of 33.5 barrels of crude oil per day. Test at a=0.01.use two tailed.
Assume that an internet provider monitors the amount of time that every customer accesses their home internet connection each day. The amount of time that all of their customers access their home internet connection is normally distributed. They access it for an average of 8.9 hours per day with a standard deviation of 2.1 hours. What proportion of samples of 100 will spend less than an average of 9 hours on their home internet per day? Your answer should have 4 decimal places.
