A process that manufactures steel bolts is supposed to be calibrated to produce bolts with a mean
length of 5 cm. A sample of 100 bolts has a mean length of 5.02 cm with a standard deviation of 0.06
cm. Let μ be the mean length of bolts manufactured by this process.
a. Find the P-value for testing 0 1 H : μ = 5 versus H : μ ≠ 5 .
b. Do you believe it is plausible that the process is properly calibrated, or are you convinced that
it is out of calibration? Explain.

In a process that manufactures tungsten-coated silicon wafers, the target resistance for a wafer is 85 m. In a simple random sample of 50 wafers, the sample mean resistance was 84.8 m, and the standard deviation was 0.5 m. Let μ represent the mean resistance of the wafers manufactured by this process. A quality engineer tests H_0:μ=85 versus H_1:μ≠85. a) Find the P-value. b) Do you believe it is plausible that the mean is on target, or are you convinced...

A process that manufactures glass sheets is supposed to be calibrated so that the mean thickness  of the sheets is more than 4 mm. The standard deviation of the sheet thicknesses is known to be well approximated by σ = 0.20 mm. Thicknesses of each sheet in a sample of sheets will be measured, and a test of the hypothesis H_0:μ≤4 versus H_1:μ>4 will be performed. Assume that, in fact, the true mean thickness is 4.04 mm. a) If...

The process that makes the spaghetti noodles for Delectable Delights is supposed to produce noodles with an average length of 252 mm.   Allison, the Quality Control Manager, is concerned that Machine #42 is not working properly and the noodles it produces are too short. You are asked to take a random sample of 40 noodles from Machine #42 and perform a hypothesis test to determine if the noodles produced by the machine are, on average, less than 252 mm. Use...

A machine is required to produce bolts with an average length of 2.00 cm. A random sample of 120 bolts had a mean length of 1.991 cm and a standard deviation of 0.766 cm. (a) [7] Does the sample provide sufficient evidence that the machine is not operating properly? Test an appropriate hypothesis at α = 0.01. (b) [5] Make a 99% confidence interval for the average length. What additional information does it provide over the test in (a)? (c)...

A production process for steel rods used to reinforce concrete is known to produce rods whose lengths have a variance of 64 cm. The production machinery has been set to produce rods with a mean of (600 centimeters, cm), in length. These rods are tied into bundles of 40 for shipment to construction sites. What is the probability that the average length of a randomly selected bundle is less than 598 cm? What is the probability that the average length...

The Glen Valley Steel Company manufacturers steel bars. If the production process is working properly, it turns out steel bars with mean length of a least 2.8 feet with a standard deviation of 0.20 foot (as determined from engineering specifications on the production equipment involved). Longer steel bars can be used or altered, but shorter bars must be scrapped. You select a sample of 25 bars and the mean length is 2.73 feet. Do you need to adjust the production...

Problem 7: The Glen Valley Steel Company manufactures steel bars. If the production process is working properly, it turns out steel bars with mean length of at least 2.8 feet. The quality control manager wants to determine whether the production equipment needs to be adjusted. A sample of 25 bars is selected from the production line. The sample indicates a mean length of 2.73 feet, with a sample standard deviation of 0.20 feet. Should adjustments be made to the equipment?...

Lazurus Steel Corporation produces iron rods that are supposed to be 36 inches long. The machine that makes these rods does not produce each rod exactly 36 inches long. The lengths of the rods are normally distributed and vary slightly. It is known that when the machine is working properly, the mean length of the rods is 36 inches. The standard deviation of the lengths of all rods produced on this machine is always equal to 0.035 inch. The quality...
