n a typical car, bell housings are bolted to crankcase castings by means of a series of 13 mm bolts. A random sample of 12 bolt-hole diameters is checked as part of a quality control process and found to have a variance of 0.0013 mm2. Find the 90% Confidence interval for the population standard deviation.

The manufacturer of a particular brand of tires claims they average at least 50,000 miles before needing to be replaced. From past studies of this tire, it is known that the population standard deviation is 8,000 miles. A survey of tire owners was conducted. From the 23 tires surveyed, the mean lifespan was 40500 miles. Using alpha = 0.05, can we prove that the data is inconsistent with the manufacturers claim? We should use a test. What are the correct hypotheses? H0: Ha: Based on the hypotheses, find the following:Test Statistic=p-value= The correct decision is to . The correct conclusion would be:
A major car manufacturer wants to test a new engine to determine whether it meets air pollution standards. The mean emission levels of all engines must be not more than 60 parts per million (ppm) of carbon. 10 engines are manufactured for test and the sample mean and standard deviation are 61.1 ppm and 3.0 ppm respectively. Do these data provide sufficient evidence to conclude that this engine does not meet the pollution standards? Using 5% level of significance.
A company need to estimate the average weight of a product at 95% level of confidence. Average weight and standard deviation of a sample of size 50 are 20.5 kg and 4.8 kg respectively. Estimate the average weight of the total production.
To run without causing damage, diameters of engine crankshafts for a certain car model must fall between 223.92mm and 224.08mm. Crankshaft diameters are normally distributed, with a mean of 224mm and a standard deviation of 0.03mm. What percentage of these crankshafts are likely to cause damage?
Oil field studies have shown that permeability measurements are having a normal distribution with a mean of 68 uD and a standard deviation of 10 µD. Determine the permeability that is exceeded by 90% of the samples.
The mean of the commute time to work for a resident of a certain city is 27.3 minutes. Assume that the standard deviation of the commute time is 7.1 minutes. What minimum percentage of commuters in the city has a commute time within 2.5 standard deviations of the mean? What are the commute times within 2.5 standard deviations of the mean?
The mean consumption of water per household in a city was 1239 cubic feet per month Due to a water shortage because of a drought, the city council campaigned for water use conservation by households. A few months after the campaign was started, the mean consumption of water for a sample of 92 househoids was found to be 1157 cubic feet per month. The population standard deviation is given to be 251 cubic feet a. Find the p-value for the hypothesis test that the mean consumption of water per household has decreased due to the campaipn by the city council. Would you reject the null hypothesis at a = 0.025? Round your answer to four decimal places. pvalue =i We b. Make the test of part a using the critical-value approach and a = 0.025. Round your answer for z to two decimal places. Zoberved We We conclude that the mean consumption of water per household has due to the campaign by the city council.
An EQ Test was administered to random sample of 130 grade school pupils. The sample mean was 95.8 with standard deviation of 10. Find 99% confidence interval.
A manufacturing process produces a critical part of average length 80 millimeters, with a standard deviation of 3 millimeters. All parts deviating by more than 5 millimeters from the mean must be rejected. What percentage of the parts must be rejected, on average? Assume a normal distribution.
A market research group would like to know the satisfaction of subscribers in terms of the quality of service provided by Smart Communications and Globe Telecom. Using a survey, they gathered data from two independent samples. The data below summarizes the average customer satisfaction score (out of 10) towards the quality of services of their mobile providers. The satisfaction score is assumed to be normally distributed with unknown and UNEQUAL population variances. Statistics Smart Communications Globe Telecom Mean 4.20 3.15 Standard Deviation 1.25 2.25 Sample Size 25 20 a) Is there a difference in the average satisfaction scores of subscribers from Smart Communications and Globe Telecom? Make the comparisons at the 10% and 5% levels of significance. b) On average, are subscribers from Smart Communications more satisfied with their service provider than from the subscribers from Globe Telecom? Use the 5% and 1% levels of significance.
A peditrician claimed that the average time for a drug to take effect is 15 minutes with standard deviation of eight minutes. In sample of 49 trials the average time was 18 minutes. Test the claim of a pediatrician that the average time is not equal to 15 minutes. Assume the the average time for a drug to take effect is approximately normal distributed
