Company ABC claims that they produces cans whose diameters are normally distributed with a population mean of 2 inches and a population standard deviation of 0.06 inch. A customer wants to check if the mean diameter of the cans is different than 2 inches. He takes a random sample of nine samples and finds a sample mean of 1.95 inches. Use a significance level of α = 0.07 to perform a hypothesis test using p value approach.
Answer key: Two sided test
Z stat = -2.5
P value = (2 X 0.0062) = 0.0124
Reject null hypothesis
(Please show the work step by step with figure, decision rule and decision.)

A cereal company claims that mean weight of cereal boxes is at most 16.1 ounces. Suppose that a plant manager wishes to test whether the true mean weight of cereal boxes is greater than 16.1 ounces. Suppose that for this problem the population standard deviation is 0.4 and the population distribution is normal. The manager obtain a random sample of size 25 and finds a mean of 16.3 ounces. Using p value approach test the claim of company at significance...
The manufacturer of aerosol spray cans claims that cans must be able to withstand pressures, on...
The manufacturer of aerosol spray cans claims that cans must be able to withstand pressures, on average, greater than 500 lb/in2. Based on previous experience, it is assumed that the pressure that the cans fail is well-approximated by a normal distribution. Suppose 16 cans are randomly selected and subjected to pressure until they fail. Given that the mean failing pressure for this sample came out to be 507.6 lb/in2 and the standard deviation of this sample turned out to be...
The distribution of piston diameters is normally distributed with mean μ inches and standard deviation 5...
The distribution of piston diameters is normally distributed with mean μ inches and standard deviation 5 inches. Engineer Dan takes a sample of 25 pistons from the manufacturing assembly line. Let X1, X2, ..., X25 denote these observations which are iid (independently & identically distributed). a.) What is the probability that X-bar, the sample mean of Dan's 25 observations, is within 1 inch of the population mean μ? b.) Suppose engineer Jane decides to take a sample of 30 observations....

A company claims that the mean volume of the soda in its cans is 12.0 ounces. In a random sample of 8 of its cans, the mean is found to be 12.1 ounces. Based on past research, the population standard deviation is assumed to be 0.1 ounces. Test the claim that the mean is 12.0 ounces. Use a 0.01 level of significance. a) State the null and alternative hypotheses. b) Find the value of the test statistic. Use the appropriate...

5. The diameters of steel shafts produced by a certain manufacturing process should have a mean diameter of 0.255 inches. The diameter is known to have a standard deviation of σ= 0.0001 inch. A random sample of 10 shafts has an average diameter of 0.2545 inches. (a) Set up the appropriate hypotheses on the mean μ (b) Test these hypotheses using α: 0.05, what are your conclusions? (c) Find the P-value for this test. P 2.6547x1055
A manufacturing process produces Ping-Pong balls with diameters that have a normal distribution with known population...
A manufacturing process produces Ping-Pong balls with diameters that have a normal distribution with known population standard deviation of .04 centimeters. Ping-Pong balls with diameters that are too small or too large are considered defective. The manufacturing company claims all their Ping-Pong balls have a diameter of exactly = 0.50 centimeters. Perform a hypothesis test at the 5% level of significance to check if the claim is true. Assume that a random sample of 25 gave a mean diameter of...

2. One Sample t-test for Population Mean A vendor claims that the average weight of a shipment of parts is 1.84. The customer randomly chooses 64 parts and finds the sample has an average of 1.88 and standard deviation of 0.03. Should the customer reject the lot? Assume the customer wants to be 95% confident that the supplier's claim is incorrect before he rejects. (This is the same as the last example, except that 0.03 is the sample standard deviation...

A supplier claims the mean thickness of its washers is 0.75 inches. Washers that are too big or too small can cause problems in the machines. A sample of 50 finds xbar = 0.73 inches and s = 0.08 inches. Test the supplier's claim. What is the null hypothesis? What is the p-value? Remember to consider whether it is a one-tailed or two-tailed test. Draw a conclusion.
