2.) A manufacturer produces crankshafts for an automobile engine. The crankshaft's diameter (3cm) is of interest because it is likely to have an impact on warranty claims. A random sample of n=15 shafts is tested and = 2.78em. It is known that the true deviation in wear is 0.9cm and the wear is normally distributed. Is there evidence that the diameter of the crankshafts is not 3cm? Show all work! Step 1: Step 2: Step 3: Step 4: Step 5:...

The piston rings are used to reject when a certain dimension is not within the specifications 2.0±d. It is known that this measurement is normally distributed with mean 1.50 mm and standard deviation 0.20 mm. (4). Find the value d such that the specifications cover 90% of the measurements. (5). What is the probability that the measurement of a selected piston ring will be more than 3 mm?

Historically data shows that the diameter of current piston rings is a normally distributed random variable with mean of 12 CM and standard deviation of 0.04 CM A. If you use 46 randomly select the rings and calculate X bar what is the probability of having an X bar greater than 12.01cm B. Assume you take 40 rings and put them side-by-side in line what is the probability that the length of the line will exceed 490cm? use original sd

A polymer is manufactured in a batch chemical process. Viscosity measurements show that it is approximately normally distributed with a standard deviation of σ = 20. A random sample of 42 batches has a mean viscosity, x-bar = 759. Construct a 99% confidence interval around the true population mean viscosity.

statistics question? It was found that the producer of the O-Rings that were used by the space shuttle Challenger were not consistent. From past production, the population standard deviation of ring diameters produced had found to be σ = 0.053 inches. For a simple random sample of n = 30 O-Rings, the average diameter was found to be 1.400 inches. Construct a 95% confidence interval and interpret the results.
