Suppose that the gasoline mileage is approximately normally distributed with a standard deviation of 3.2 miles per gallon. 2. What conditions must n satisfy to make the x2 test valid? 3. To use the t-statistic to test for a difference between the means of two populations, what assumptions must be made about the two populations? About the two samples? 4. Studies of managers from two countries in the 1970s found sharp differences of opinion toward quality management. To find out if these differences continue to exist, researchers surveyed 100 managers in each country in the electronics manufacturing industry. The accompanying table gives the percentages of managers from each country who agree with each of 10 randomly selected statements regarding quality.

  • A random sample of size 15 is selected from a
    normal population. The population standard
    deviation is unknown. Assume the null hypothesis
    indicates a two-tailed test and the researcher
    decided to use the 0.10 significance level. For
    what values of t will the null hypothesis not be
    rejected?

    business travelers are asked which Midwestern
    city they prefer Indianapolis, Saint Louis,
    Chicago or Milwaukee. 388 liked Indianapolis
    best, 450 liked Saint Louis, 1212 liked Chicago
