Using the three out-of-control criteria, is the statistical process within control?OA. Yes, because none of the criteria are satisfied.OB. No, because there are eight or more consecutive points all above or all below the centerline.OC. No, because there is a pattern, trend, or cycle that is obviously not random.OD. No, because there is at least one point lying outside of the region between the upper and lower control limits.c. Choose the correct answer below.OA. The manufacturer should proceed as before, because the number of defects is decreasing and the production process appears to be improving.OB. The manufacturer should proceed as before, because the number of defects is increasing.OC. The manufacturer should review their production process and attempt to remedy the cause of increasing proportions of defects.OD. The manufacturer should review their production process and attempt to remedy the cause of increasing variation in the proportions of defects.

A time analyst for the Super-Fast speedway pit crew observed the mechanic in charge of changing both front tires during a pit-stop practice session. The mechanic’s job is divided into six work elements and a preparation time between drills. The element times (in seconds) for the first six cycles are shown in Table.a. Calculate the normal time for changing tires.b. What sample size is appropriate for estimating the average time for work element 3 within +-1 percent of the true mean with 99 percent confidence?c. What is the standard time for changing tires if the allowance is 20 percent?
An immunologist wants to compare two rabies vaccines. People who had previously received the vaccine were divided into two groups. The first group received a booster dose of type I vaccine and the second group received a booster dose of type II vaccine. Two weeks later the antibody level was measured. The average number of antibodies in each group appears in the following table: Do these data indicate that there is a difference in the effectiveness of the two vaccines used for booster doses? Assume a normal distribution and equal population variances. What type of hypothesis test will allow us to reach a conclusion in the situation posed above? A. Variance test B. Unilateral for difference in proportions C. Bilateral for average difference D. Unilateral for change in effectiveness
