A manufacturer produces piston rings for an automobile engine. It is known that ring diameter is approximately normal distributed and has standard deviation σ = 25 hours. A random sample of 62 bulbs has a mean life of x-bar = 74.036 mm. Construct a 90% confidence interval around the true population mean for piston ring diameter.

Amanufacturer produces piston rings for an automobile engine. It is known that ring diameter is normally distributed with o = 0.001 millimeters. A random sample of 15 rings has a mean diameter of t = 74.050. Construct a 99% two-sided confidence interval on the true mean piston diameter and a 95% lower confidence bound on the true mean piston diameter. Round your answers to 3 decimal places. (a) Calculate the 99% two-sided confidence interval on the true mean piston diameter....

3. A semiconductor manufacturer produces controller used in automobile engine applications. The customer requires that the process fallout or fraction defective at a critical manufacturing step not exceed 0.05 and that the manufacturer demonstrate process capability at this level of quality using a 0.05. The semiconductor manufacturer takes a random sample of 200 devices and finds that four of them are defective. Can you check the (3 points) manufacturer claim?

The manufacturer of a certain engine treatment claims that if you add their product to your engine, it will be protected from excessive wear. An infomercial claims that a woman drove 4 hours without oil, thanks to the engine treatment. A magazine tested engines in which they added the treatment to the motor oil, ran the engines, drained the oil, and then determined the time until the engines seized. Complete parts (a) and (b) below. Determine the null and alternative...

2. An automobile manufacturer wants to estimate the mean gasoline mileage that its customers will obtain with its new compact model. It is known that gasoline mileage for this model is normally distributed with a population standard deviation of 2.5 miles per gallon. In a sample of n=16 test runs the average mileage was 28 mpg. Construct a 98% confidence interval for the true mean gasoline mileage for this new compact model. Show your work
