A tire manufacturer has a 60,000 mile warranty for tread life. The Select one answer. manufacturer considers the overall tire quality to be acceptable if less 10 points than 5% are worn out at 60,000 miles. The manufacturer tests 250 tires that have been used for 60,000 miles. They find that 3.6% of them are worn out. With this data, we test the following hypotheses. Ho: The proportion of tires that are worn out after 60,000 miles is equal to 0.05. He: The proportion of tires that are worn out after 60,000 miles is less than 0.05. In order to assess the evidence, which question best describes what we need to determine? A. If we examine the proportion of worn out tires in the population of tires used for 60,000 miles, how likely is that proportion to be 5%? B. . If we examine the proportion of worn out tires in the population of tires used for 60,000 miles, how likely is that proportion to be less than 5%? C. If we examine a sample of tires used for 60,000 miles and determine the proportion that are worn out, how likely is that proportion to be less than 5%? D. . If we examine a sample of tires used for 60,000 miles and determine the proportion that are worn out, how likely is that proportion to be 3.6% or less? E. . If we examine the proportion of worn out tires in the population of tires used for 60,000 miles, how likely is that proportion to be 3.6%? Question 4 Food inspectors inspect samples of food products to see if they are Select one answer. safe. This can be thought of as a hypothesis test with the following 10 points hypotheses. . H : The food is safe. . H: The food is not safe Based on the hypotheses above, Is the following statement a Type I or Type II error? The sample suggests that the food is safe, but it actually is not safe. A. o Type I B. . Type II Question 5 Living with parents: The Pew Research Center reported that 36% Select one answer. of American Millennials (adults ages 18-31) still live at home with 10 points their parents. A group of students wants to conduct a study to determine whether this result is true for students at their campus. They survey 300 randomly selected students at their campus and determine that 43% of them still live at home with their parents. With this data, they test the following hypotheses at the 5% significance level. The p-value is 0.006. Ho: Of Millennial students at their campus, 36% live at home with their parents. H : More than 36% of Millennial students at their campus live at home with their parents. Which of the following conclusions is correct? A. Accept Ho B. Fail to reject H C. Reject H
