The DMV (the place where you get your driver’s license) hires a consultant to do something about all their complaints for wait times. They find that 75% of the visitors get through the line in less than 20 minutes. If the standard deviation of the wait time is 6.2 minutes, find the average wait time per visitor. Can you help ? I've tried but I don't think I am doing right

Levi-Strauss Co manufactures clothing. The quality control department measures weekly values of different suppliers for the percentage difference of waste between the layout on the computer and the actual waste when the clothing is made (called run-up). The data is in the table, and there are some negative values because sometimes the supplier is able to layout the pattern better than the computer. Do the data show that there is a difference between some of the suppliers? Test at the 1% level.

A psychologist is studying the self image of smokers, as measured by the self-image (SI) score from a personality inventory. She would like to examine the mean SI score, μ, for the population of all smokers. Previously published studies have indicated that the mean SI score for the population of all smokers is 82and that the standard deviation is 12, but the psychologist believes that the value for the mean has decreased. She plans to perform a statistical test. She takes a random sample of SI scores for smokers and computes the sample mean to be 7.Based on this information, answer the questions below. What are the null hypothesis (H0) and the alternative hypothesis (H1) that should be used for the test?H0: μ is ?less than less than or equal togreater thangreater than or equal to not equal toequal to ? 82 74 12 H1: μ is ?less thanless than or equal togreater thangreater than or equal tonot equal toequal to ? 82 74 12 In the context of this test, what is a Type II error?A Type…

Marjorie More Mileage is obsessed with getting the best gas mileage possible for her 2017 Toyota Prius. She learns from the official Toyota web site that the official average mileage for all 2017 Prius is = 58.2 mpg with a standard deviation of = 1.2 mpg. Marjorie purchased a set of “hyper mileage” tires on-line that are supposed to improve gas mileage. For the next 100 fill ups, Marjorie noticed an average gas mileage of = 58.5 mpg. Help Marjorie perform a hypothesis test at a 1% level of significance to determine if her new tires actually improved her gas mileage. What is the null hypothesis? What is the alternate hypothesis? Is this a left tail, right tail, or two tail test? Calculate the test statistic. State your conclusion.

Your friend Bob thought he did well on his biology test- he scored a 70. He said, he knew he did better than average as the profesor said the average was 60. He also heard his profesor say it was a normal distribution with a standard deviation of 5, but Bob has no clue what this means. Using what you know about the normal distribution, explain how Bob's score of 70 compares to Dave's score of 55.
