A researcher wants to conduct a before/after study on 11 subjects to determine if a treatment results in any difference in scores. The null hypothesis is that the average difference is zero while the alternative hypothesis is that the average difference is not zero. Scores are obtained on the subjects both before and after the treatment. After subtracting the after scores from the before scores, the average difference is calculated to be –2.40 with a sample standard deviation of 1.21. Assume that the differences are normally distributed in the population. The degrees of freedom for this test are _______.
A、11
B、10
C、9
D、20
A、do not reject the null hypothesis
B、reject the null hypothesis
C、take a larger sample
D、use the z-table instead of the t-table
Cowra Construction Company purchases steel rods for its projects. Based on previous tests, Clarrie Carter, Quality Assurance Manager, has recommended purchasing rods from Redding Rods (population 1), rather than Stockton Steel (population 2), since Redding’s rods had less variability in length. Recently, Stockton revised it rod shearing operation, and Clarrie has sampled the outputs from Redding’s and Stockton’s rod manufacturing processes. The results for Redding were s12 = 0.10 with n1 = 8, and, for Stockton, the results were s22 = 0.05 with n2 = 10. Assume that rod lengths are normally distributed in the population. Clarrie’s alternate hypothesis is __________________.
A、s12 = s22
B、s12 ≠ s22
C、s12 > s22
D、s12 < s22
Stefan Irwin, Marketing Manager at Classic Merchandise, is investigating response rates to scented and unscented direct mail catalogues. If the response rate for the scented catalogue (population 1) is higher, Mike will adopt the scented version. His staff randomly selects two samples of 200 each from the company’s customer database. One month after the 400 test catalogues were mailed, forty-five orders (twenty-five from the scented and twenty from the unscented) were received from the test catalogues. Assuming a = .01, Mike’s alternate hypothesis is ________________.
A、p1 – p2 > 0
B、m1 – m2 = 0
C、m1 – μ2 ≠ 0
D、s12 < s22
Tamara Hill, Fund Manager with Hillcrest Value Fund, manages a portfolio of 250 common stocks. Tamara is searching for a ‘low risk’ issue to add to the portfolio, i.e. one with a price variance less than that of the S&P 500 index.

Her staff reported that during the last nine quarters the price variance for the S&P 500 index (population 1) was 25, and for the last seven quarters the price variance for XYC common (population 2) was 8. Assume that stock prices are normally distributed in the population. Using a = 0.05, the appropriate decision is _______.
A、reject the null hypothesis s12 = s22
B、eject the null hypothesis s12 ¹ s22
C、do not reject the null hypothesis s12 = s22
