Is the following statement true or false and why: If we do not reject ?0H0, then we conclude that ?1H1 is false. Washers used in a certain application are supposed to have a thickness of 2 millimeters. A quality control engineering measures the thickness for a sample of washers and tests ?0:?=2H0:μ=2 versus ?1:?≠0H1:μ≠0. If a Type I error is made, what conclusion will be drawn regarding the mean washer thickness?

10. An engineering study was undertaken to determine the optimum thickness of aluminum to be used to construct cans to be used for cat food. Cans made of aluminum of thickness 2.10 mm and 1.90 mm were tested to determine the maximum load each would sustain before collapsing. The sample data is summarized below. Use a = 0.05 to test the claim that the thicker cans are stronger (will withstand a higher load). 2.10 mm thick 1.90 mm thick sample size 175 170 mean maximum load (kg) 28.18 26.71 standard deviation of maximum load (kg) | 2.78 2.21

A company that manufactures rivets believes the shear strength (in pounds) is modeled by N(750,30). Use the 68–95–99.7 Rule to complete parts a) through c) below. a) Draw and label the Normal model. b) Would it be safe to use these rivets in a situation requiring a shear strength of 720 pounds? Explain. Choose the correct answer below. A. No, because about 32% of all of this company's rivets have a shear strength of less than 720 pounds. B. Yes, because very nearly all of this company's rivets have a shear strength of more than 720 pounds. C. No, because about 16% of all of this company's rivets have a shear strength of less than 720 pounds. D. Yes, because only about 2.5% of all of this company's rivets have a shear strength of less than 720 pounds. c) About what percent of these rivets can be expected to fall below 810 pounds?
As we noted previously, the researchers reported that “participants were run in pairs of stra We preregistered the study and collected data from 200 undergraduate and graduate stuc outside a campus café (107 female; age: M = 23.57 years, SD = 8.80)" (p. 542). What do the researchers mean when they renort "ace: M= 23 57 vears SD = 8.80"? Highlight Add Note O A. The range of participant ages is 14.77 w Jz.T, WItrune mtan, 23.57, at the center. O B.

The mean age for the participants in the study is 23.57, with a standard deviation of 8.80.
Determine whether the outcome is a Type I error, a Type II error, or a correct decision. A test is made of H0: μ = 28 versus H1: μ ≠ 28. The true value of μ is 29 and H0 is rejected.

A health insurance company conducted an independent study and collected data from a random sample of 265 individuals for prescription allergy relief medicine. The sample mean is found to be 17.5 dollars/year, with a sample standard deviation of 5.6 dollars/year. They have also collected data for non-prescription allergy relief medicine. An independent random sample of 220 individuals yielded a sample mean of 18.5 dollars/year, and a sample standard deviation of 4.5 dollars/year. Since the sample size is quite large, it is assumed that the population standard deviation of the sales (per person) for prescription and non- prescription allergy…
