Determine the appropriate decision rule for the given hypothesis test. Suppose we claim that the average GPA for all students at a University (with at least 60 hours completed) is more than 2.7. From a sample of 25 students, the average GPA is 2.85 with a standard deviation of 0.6. The GPA's are normally distributed and a = 0.10. Choose the appropriate decision rule below.

The average sales price of new one-family houses in the Midwest is $252,400 and in the South is $259,500. A random sample of 36 houses in each region was examined with the following results. At the 0.05 level of significance, can it be concluded that the difference in mean sales price for the two regions is greater than $3400? Midwest South Sample size 36 36 Sample...

Determine whether the claim stated below represents the null hypothesis or the alternative hypothesis. If a hypothesis test is performed, how should you interpret a decision that (a) rejects the null hypothesis or (b) fails to reject the null hypothesis? A researcher claims that more than 82% of people had at least one health care visit in the past year. Does the claim represent the null hypothesis or the alternative hypothesis? Since the claim v a statement of equality, it...
