A sample of 900 computer chips revealed that 63 % of the chips fail in the first 1000 hours of their use. The company's promotional literature states that 60 % of the chips fail in the first 1000 hours of their use. The quality control manager wants to test the claim that the actual percentage chat fail is different from the stated percentage. Is there enough evidence at the 0.05 level to support the manager's claim?

USA TODAY (October 14, 2016) reported that Americans spend 4.1 hours per weekday checking work email. This was an estimate based on a survey of 1,004 white-collar workers in the United States. (a) Suppose that you would like to know if there is evidence that the mean time spent checking work email for white-collar workers in the United States is more than half of the 8-hourwork day. What would you need to assume about the sample in order to use the given sample data to answer this question? (Select all that apply.) We would need to assume that all white-collar workers were surveyed or the sample is representative of the population of white-collar workers in the United States.We would need to assume that all observations are dependent or all observations are independent.We would need to assume that the distribution of the population of times is normal or that the sample size is small.We would need to assume that the sample was randomly selected or is representative of the population…
A credit score is used by credit agencies (such as mortgage companies and banks) to assess the creditworthiness of individuals. Values range from 300 to 850, with a credit score over 700 considered to be a quality credit risk. According to a survey, the mean credit score is 703.8. A credit analyst wondered whether high-income individuals (incomes in excess of $100,000 per year) had higher credit scores. He obtained a random sample of 36 high-income individuals and found the sample mean credit score to be 719.8 with a standard deviation of 81.9. Conduct the appropriate test to determine if high-income individuals have higher credit scores at the α=0.05 level of significance.
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 consumer advocacy group is doing a large study on car rental practices. Among other things, the consumer group would like to do a statistical test regarding the mean monthly mileage, µ, of car rented in the U.S. this year. The consumer group has reason to believe that the mean monthly mileage of cars rented in the U.S. this year is different from last year’s mean, which was 2700 miles. The group plans to do a statistical test regarding the value of µ. It chooses a random sample of monthly mileages and computes the mean of the sample to be 2565 miles and the standard deviation to be 800 miles. What are the null hypothesis (H0) and the alternative hypothesis (H1) that should be used for the test? H0: µ is ____ __? __ H1: µ is ____ __ ? ___ In the context of this test, what is a Type II error? A Type II error is ?________ ___ the hypothesis that µ is ? _____ ? when, in fact, µ is ? ____ Suppose that the group decided to reject the null…
There are many ways to measure the reading ability of children. One frequently used test is the DRP or Degree of Reading Power. The national average score in DRP test is 32. We want to determine if there is sufficient evidence at the 5% level to suggest that the mean score of all third graders in YOUR district is higher than the national mean. The DRP scores for a simple random sample of 41 third graders in that suburban school in YOUR district yielded a mean of 35.2. Assume that the population of DRP scores of third graders in that suburban school district are normally distributed with a population std.dev of 11.
What is a Type I error in this problem? A. A Type I error would be to conclude that the true mean level of support for sustainability is not 66 when, in fact, the mean is equal to 66. B. A Type I error would be to conclude that the sample mean level of support for sustainability is greater than 66 when, in fact, the sample mean is less than 66. C. A Type I error would be to conclude that the true mean level of support for sustainability is 66 when, in fact, the mean is not equal to 66. D. A Type I error would be to conclude that the sample mean level of support for sustainability is less than 66 when, in fact, the sample mean is greater than 66.
