Regular consumption of presweetened cereals con- tributes to tooth decay, heart disease, and other degen- erative diseases, according to studies conducted by Dr. W. H. Bowen of the National Institute of Health and Dr. J. Yudben, Professor of Nutrition and Dietetics at the University of London. In a random sample con- sisting of 20 similar single servings of Alpha-Bits, the average sugar content was 11.3 grams with a standard deviation of 2.45 grams. Assuming that the sugar con- tents are normally distributed, construct a 95% con- fidence interval for the mean sugar content for single servings of Alpha-Bits. Above and the number 9.9 attachment is the referred question of the 9.17 problem
Type I error: Washers used in a certain application are supposed to have a thickness of 2 millimeters. A quality control engineer measures the thicknesses for a sample of washers and tests H0: μ = 2 versus H1: μ ≠ 2. a. If a Type I error is made, what conclusion will be drawn regarding the mean washer thickness?
A Vape manufacturer states that its product contains on average less than 5 parts per million (ppm) of arsenic. An anti-vape group tests this claim. They tested 100 samples and found an average of 5.7 parts per million of arsenic with a standard deviation of 3.88ppm. The group used a level of significance (alpha) of .05. Determine the result of the hypothesis test.
A soft drink bottler purchases glass bottles from a vendor. The bottles are required to have an internal pressure of at least 150 pounds per square inch (psi). A prospective bottle vendor claims that its production process yields bottles with a mean internal pressure of 157 psi and a standard deviation of 3 psi. The bottler strikes an agreement with the vendor that permits the bottler to sample from the production process to verify the claim. the bottler randomly selects 40 bottles from the last 10000 produced, measures the internal pressure of each, and finds the mean pressure for the sample to be 0.8 psi below the process mean cited by the vendor. If the standard deviation were 3 psi as claimed, but the mean was 157.8 psi, what is the probability of obtaining a sample mean of 156. 2 psi or below? If the process mean were 157 psi as claimed, but the standard deviation was 2.3 psi, what is the probability of obtaining a sample mean of 156.2 psi or below?
Blood glucose levels for obese patients have a mean of 100 with a standard deviation of 15. A researcher thinks that a diet high in raw cornstarch will have a positive or negative effect on blood glucose levels. A sample of 30 patients who have tried the raw cornstarch diet have a meanglucose level of 140. Test the hypothesis that the raw cornstarch had an effect (alpha = 5%).
A simple random sample of 26 filtered 100-mm cigarettes is obtained from a normally distributed population, and the tar content of each cigarette is measured. The sample has a standard deviation of 0.22 mg. Use a 0.05 significance level to test the claim that the tar content of filtered 100-mm cigarettes has a standard deviation different from 0.35 mg, which is the standard deviation for unfiltered king-size cigarettes.
