A semiconductor manufacturer produces controllers used in automobile engine applications. The customerrequires that the process fallout or fraction defective at a critical manufacturing step be less than 0.05 andthat the manufacturer demonstrate process capability at this level of quality using alpha 0.05. Thesemiconductor manufacturer takes a random sample of 200 devices and finds that four of them aredefective. Can the manufacturer demonstrate process capability for the customer?a. What is the appropriate alternative hypothesis for this test? H1:b. The critical value is-(Write your answer precise to 2 decimal places, e.g. 2.45, 3.01,4.00)c. The z test statistic is. (Write your answer precise to 2 decimal places, e.g. 2.45, 3.01,4.00)d. The P-value is equal to. (Give the exact value from the standard normal table used inclass.)e. The correct decision is to (reject or not reject)Ноf. The correct conclusion is that there is (significant or insignificant)sample evidence toshow that the manufacturer (demonstrates or does not demonstrate)process capabilityfor the customer.

The average worker at a local brake manufacturer produces 10 brakes per day (other statistical information was not known). An industrial psychologist was hired to increase worker productivity and a new assembly method was designed and tested in a sample of workers. Identify the appropriate test.

A study of road rage asked random samples of 596 men and 523 women about their behavior while driving. Based on their answers, each person was assigned a road rage score on a scale of 0 to 20. The participants were chosen by random digit dialing of phone numbers. The researchers performed a test of the following hypotheses: Ho: μM=μF versus Ha: μM≠μF.Ho: μM=μF versus Ha: μM=μF. The P-value for the stated hypotheses is 0.002. Interpret this value in the context of this study. A) Assuming that the true mean road rage score is the same for males and females, there is a 0.002 probability of getting a difference in sample means. B) Assuming that the true mean road rage score is the same for males and females, there is a 0.002 probability of getting an observed difference at least as extreme as the observed difference. C) Assuming that the true mean road rage score is different for males and females, there is a 0.002 probability of getting an observed difference at least as…
Miller (2008) examined the energy drink consumption of college undergraduates and found that males use energy drinks significantly more often than females. To further investigate this phenomenon, suppose that a researcher selects a random sample of n=36 male undergraduates and s ample of n=25 females. On average, the males reported consuming M=2.45 drinks per month and females had an average of M=1.28. Assume that the overall level of consumption for college undergraduates averages μ=1.85 energy drinks per month, that that the distribution of monthly consumption scores is approximately normal with a standard deviation of σ=1.2. Did this sample of males consume significantly more energy drinks than the overall population average? Use a one-tailed test with α =0.01. Did this sample of females consume significantly fewer energy drinks than the overall population average? Use a one-tailed test with α =0.01.
Dr. Ingrid is conducting an experiment to see whether time spent reading is related to poor vision. To do so, she creates three groups and randomly assigns 17 participants to each: the first group reads for 30 min a day, the second group reads for 1hr a day, and the third group reads for 1.5 hrs a day. Dr. Ingrid plans on using a one-way ANOVA to analyze the results of her experiment. If Dr. Ingrid has set alpha to .01, what will be her critical value of F?
The Board of Transportation and Safety (BTS) wants to examine the safety mechanisms of A, B, and C-class cars. Samples of 10 cars for each class were used.

A large cookie company claims the average amount of sodium per cookie is 200 mg. You suspect that the sodium content is different than that, so you take a random sample of 36 cookies and research the nutritional content. You then conduct a hypothesis test that μ = 200 vs. the alternative that μ ≠ 200. (a) The standardized test statistic for your sample is 2.7. The P-value would then be: A) 0.9965 B) 0.4983 C) 0.0070 D) 0.0035 Selection: (b) Which would be the correct decision for your hypothesis test? A) Reject H0 B) Do not reject H0 Selection: (c) A Type I Error in this situation would be: A) Concluding that μ ≠ 200 when in fact μ = 200 is true. B) Concluding that μ = 200 when in fact μ ≠ 200 is true. C) Concluding that μ = 200 when in fact μ = 200 is true. D) Concluding that μ ≠ 200 when in fact μ ≠ 200 is true. Selection:
A manufacturer of children's vitamins claims that its vitamins are mixed so that each batch has exactly the following percentages of each color: 20 % green, 30 % yellow, 30% red, and 20% orange. To test the claim that these percentages are incorrect, 100 bottles of vitamins were sampled and the colors of the vitamins were tallied. The results are listed in the following table. At a = 0.025, determine whether there is sufficient evidence to conclude that the percentages stated by the vitamin manufacturer are incorrect.

In a 4-week study about the effectiveness of using magnetic insoles to treat plantar heel pain, 51 subjects wore magnetic insoles and 47 subjects wore nonmagnetic insoles. The results are shown at the right. At α=0.06, can you support the claim that there is a difference in the proportion of subjects who feel better between the twogroups? Assume the random samples are independent. Complete parts (a) through (e).
Contaminated water: Polychlorinated biphenyls (PCBS) are a group of synthetic oil-like chemicals that were at one time widely used as insulation in electrical equipment and were discharged into rivers.

I chose option 1. I believe that the population mean number of times that adults eat fruit with their breakfast is greater than 3 times. I spoke with 14 adults and found that they had fruit with breakfast 7,2,3,0,0,0,4,7,7,7,4,4,5,and 0 times in the past week. Test this hypothesis at the .05 significance level and assume a random sample.
