A business students claims that on average an MBA students is required to prepare more than five cases per week. To examine the claim, a statistics professor ask a random sample of ten MBA students to report the number of cases they prepare weekly. The results are given below. Can the professor conclude that the claim is true, at the .05 level of significance, assuming the number of cases is normally distributed with a standard deviation of 1.5?

1) Is the test statistic for this test Z or t?

2) What is the value of the test statistic of the test? ( Enter 0 if this value cannot be determined with the given information.)

3) What is the pvalue of the test? (Enter 0 if this value cannot be determined with the given information.)

4) What is the relevant bound of the rejection region? (Enter 0 if this value cannot be determined with the given information.)

5) What decision should be made?

Select one:

a. Do not reject the null hypothesis

b. Accept the null hypothesis

c. Can not be determined from given information

d. Reject the null hypothesis

A laboratory technician claims that on average it takes her no more than 7.5 minutes to perform a certain task. A random sample of 20 times she performed this task was selected and the average and standard deviation were 7.9 and 1.2, respectively. At α = 0.05, does this constitute enough evidence against the technician's claim? Use the rejection point method.

A diet doctor claims Australians are, on average, overweight by more than 10kg. To test this claim, a random sample of 100 Australians were weighed, and the difference between their actual weight and their ideal weight was calculated and recorded.
