5. A manufacturing company produces metal pipes with a desired width of 2.5 cm. Due tomachine error, the pipes vary somewhat from this target. The company takes a sample of100 pipes produced. The observed mean pipe width was approximately 2.502 and thesample standard deviation was 0.00932. The company also determined that the cutoffmeasurement for the widest 2.5% of pipes that were observed is 2.519.a.The research department of the company believes that the width of the pipes isnormally distributed, with a mean of 2.5 cm and a standard deviation of 0.01. If thatis the case, what should the cutoff be for the widest 2.5% of pipes be?b. Using any of the information above, do you think the research department's beliefsabout the distribution of the tube widths are plausible? Explain your reasoning.(Hint: How do the observed mean, standard deviation, and percentile cutoffscompare to the research's teams baseline assumptions?)

To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 42 feet. Assume the population standard deviation is 4.7 feet. The mean braking distance for Make B is 45 feet. Assume the population standard deviation is 4.4 feet. At a = 0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles?

An energy company wants to choose between two regions in a state to install energy-producing wind turbines. A researcher claims that the wind speed in Region A is less than the wind speed in Region B. To test the regions, the average wind speed is calculated for 60 days in each region. The mean wind speed in Region A is 13.8 miles per hour. Assume the population standard deviation is 2.8 miles per hour. The mean wind speed in Region B is 15.1 miles per hour. Assume the population standard deviation is 3.1 miles per hour. At a = 0.05, can the company support the researcher's claim? Complete parts (a) through (d) below. C.

The diameter of a spindle in a small motor is supposed to be 4.4 millimeters (mm) with a standard deviation of 0.11 mm. If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of 15 spindles to determine whether the mean diameter has moved away from the required measurement. Suppose the sample has an average diameter of 4.27 mm. H0: Ha: (b) Harry thinks that prices in Caldwell are lower than the rest of the country.
