2. A crush resistance testing of steel plate produced by a manufacturer have mean 1800 kg and standard deviation 100 kg. By a new technique in the manufacturing process it is claimed that the crush resistance can be increased. To test this claim, a sample of 50 stee plates is tested, and it is found that the mean crush resistance is 1850 kg. (a) Can we support the claim at a 0.01 level of significance? (b) What is the P-value of the test?

0) A coin-operated drink machine was designed to discharge a mean of 7 fluid ounces of coffee per cup. In a test of the machine, the discharge amounts in 18 randomly chosen cups of coffee from the machine were recorded. The sample mean and sample standard deviation were 7.19 fluid ounces and 0.28 fluid ounces, respectively. If we assume that the discharge amounts are approximately normally distributed, there enough evidence, to conclude that the population mean discharge, µ, differs from 7 fluid ounces? Use the 0.05level of significance
A random sample of 225 nails in a manufacturing company is gathered. The engineer specified length of a nail must be 8 centimeters having a standard deviation of 0.04 centimeters. It shows that the average weight of the nails is 8.055 centimeters. Do the produced nails exceed the specification of the engineer at a 1% level of significance. 1. What is the level of significance of the problem? 2. What is the critical value of the problem?
Researchers measured the length of time people spend brushing their teeth. For the 154 subjects in their study, the mean was 72.8 seconds with a standard deviation of 23. 5 seconds. Use this information with a 0.10 significance level to test the claim that the mean teeth brushing time was less than 80 seconds. What is/are the critical value(s)?

The yield is observed for 90 batches of ceramic substrate to which a metal coating is applied by a vapor-deposition process. Test the null hypothesis that the mean yield is 90.0 versus the alternative hypothesis that it is different from 90.0, using α = 0.05. Show all parts of the test, including the p-value and how you use it to reach your conclusion. Mean=89.3756, Standard deviation=4.3159
An article shows data to compare several methods for predicting the shear strength for steel plate girders. Data for two of these methods, the Karlsruhe and Lehigh procedures, when applied nine times to a girder, are shown in the following table. We wish to determine whether there is any difference between the two methods. Assume the same standard deviations. (Note that we will perform unpaired comparison. We do not perform a paired test.)

Daily Driving The average number of miles a person drives per day is 24. A researcher wishes to see if people over age 60 drive less than24 miles per day. She selects a random sample of 25 drivers over the age of 60 and finds that the mean number of miles driven is 23.4. The population standard deviation is 4.1 miles. At=α0.01, is there sufficient evidence that those drivers over 60 years old drive less than 24 miles per day on average? Assume that the variable is normally distributed. Use the critical value method with tables. State the hypotheses and identify the claim with the correct hypothesis. :H0 =μ24 ▼not claim :H1 <μ24 ▼claim the hypothesis test is a ▼one-tailed test. Part 2 of 5 Find the critical value(s). Round the answer to at least two decimal places. If there is more than one critical value, separate them with commas. Critical value(s):
