USE THE 8-STEP HYPOTHESIS TESTING In a study by Xiao and Shi (A-14), researchers studied the effect of cranberry juice in the treatment and prevention of Helicobacter pylori infection in mice. The eradication of Helicobacter pylori results in the healing of peptic ulcers. Researchers compared treatment with cranberry juice to "triple therapy (amoxicillin, bismuth subcitrate, and metronidazole) in mice infected with Helicobacter pylori. After 4 weeks, they examined the mice to determine the frequency of eradication of the bacterium in the two treatment groups. The following table shows the results. Triple therapy Cranberry juice No. of Mice with Helicobacter pylori Eradicated Yes No 8 2 2 8 Source: Shu Dong Xiao and Tong Shi, "Is Cranberry Juice Effective in the Treatment and Prevention of Helicobacter Pylori Infection of Mice," Chinese Journal of Digestive Diseases, 4 (2003), 136-139. May we conclude, on the basis of these data, that triple therapy is more effective than cranberry…

A blind taste test is conducted to determine which of two colas, Brand A or Brand B, individuals prefer. Individuals are randomly asked to drink one of the two types of cola first, followed by the other cola, and then asked to disclose the drink they prefer. Results of the taste test indicate that 58 of 100 individuals prefer Brand A. Complete parts a through c. (a) Conduct a hypothesis test (preferably using technology) H0:p=p0 versus H1:p≠p0 for p0=0.47,0.48,0.49,...,0.67,0.68,0.69 at the α=0.05 level of significance. For which values of p0 do you not reject the null hypothesis? What do each of the values of p0 represent? Do not reject the null hypothesis for the values of p0 between _ and _,inclusively.
You watch people exiting Dodgers stadium after a game and you write down the number of males and the number of females that exit the stadium past you during the 20 minutes that you spend watching. You assumed that there would be a perfectly equal number of males and females attending a Dodgers game, but you look at the number of males and females that you actually counted, and you see if you still think that is actually true. What kind of hypothesis test would allow you to do this? a. One-Factor, Independent-Measures ANOVA b. Two-Factor ANOVA c. Correlation/Regression d. Chi-Square Goodness of Fit
