A company makes windows for use in homes and commercial buildings. The standards for glass thickness call for the glass to average 0.4000 inch with a standard deviation equal to 0.0500 inch. Suppose a random sample of n=48 windows yields a sample mean of 0.4190inch. Complete parts a and b below. a. P(xbar more than 0.419)= 0.0043 b. . Based on your answer to part a, what would you conclude about the population of windows? Is it meeting the standards?...

A company makes windows for use in homes and commercial buildings. The standards for glass thickness call for the glass to average 0.500 inch with a standard deviation equal to 0.045 inch. Suppose a random sample of n=51 windows yields a sample mean of 0.519 inch. What is the probability of getting a sample mean greater or equal to 0.519, if the windows meet the standards? (Round to four decimal places as needed.)

l. Armbrister Windows makes windows which have a production standard of an average of 0.375 inches thick with a standard deviation of 0.050 inches. A random sample of 64 windows yields an average of 0.382 inches. Calculate the probability of obtaining a random sample of 64 windows with an average of at least 0.382 inches. 2.

A quality manager is concerned with the thickness of test coupons for a ballistic test according to MIL-STD-662F, a military standard for testing. The nominal thickness for test specimen is 0.375 inches. Suppose you are testing the population mean thickness, µ, of the specimen using the following hypotheses: H0 : µ = 0.375 vs. HA : µ 6= 0.375 (a) Suppose we reject the null hypothesis when the true value of the mean thickness is 0.380 inches. Did we commit...

A machine at Katz Steel Corporation makes 3-inch-long nails. The probability distribution of the lengths of these nails is approximately normal with a mean of 3 inches and a standard deviation of 0.12 inch. The quality control inspector takes a sample of 25 nails once a week and calculates the mean length of these nails. If the mean of this sample is either less than 2.95 inches or greater than 3.05 inches, the inspector concludes that the machine needs an...

A factory produces plate glass with a mean thickness of 4mm and a standard deviation of 1.1mm. A simple random sample of 100 sheets of glass is to be measured, and the mean thickness of the 100 sheets is to be computed. What is the probability that the average thickness of the 100 sheets is less than 4.13 mm? Round your answers to 5 decimal places.

During the manufacturing of commercial windows, hot steel ingots are passed though a rolling process and flattened to a prescribed thickness. When the manufacturing process is working properly the ingots should have a mean thickness of 0.75 inches. A random sample of 40 ingots is taken and the mean was found to be 0.725 inches with a standard deviation of 0.092. a. Find a 95% confidence interval for the population mean thickness. b. Find the error bound. c. Interpret the...
