Chapter 6, Problem 29P

Suppose a clinical trial is conducted to test the efficacy of a new drug, spectinomycin, for treating gonorrhea in females. Forty-six patients are given a 4-g daily dose of the drug and are seen 1 week later, at which time 6 of the patients still have gonorrhea

Suppose we know penicillin G at a daily dose of 4.8

megaunits has a 10% failure rate. What can be said in comparing

the two drugs?

A Dr is doing a test on diseases. He has a population of 1,000,000 with a disease affecting .01% of the population. There is a test for the disease which is 99% accurate. A positive test result indicates that the person has the disease. How would I complete the table below assuming that the entire population (1,000,000 individuals) is tested for the disease?
A company is testing a new drug and wants to determine what is the most effective dose in reducing the size of cancerous tumors. The company randomly select a sample of 32 individuals and randomly assigns them into 4 groups of 8 each. One group get 5mg of drug x, a second group get 10mg, a third group gets 15 mg, and the fourth group gets 20mg. After two months the company finds the average size of the tumors to be 40mm, 37mm, 26mm, and 12mm for each group, respectively. (1) State the null and alternative hypotheses for this study (2) What is the dependent and independent variable for this study (3) What test statistic/hypothesis test would you select to determine if the means are significantly difference at the alpha .05 level? (4) What critical value would you use to make your decision to reject or retain the null hypothesis at alpha .05?
Suppose we want to study the effect of smoking on lung capacity in women. Match the study to experimental or observational.                                       Find 100 women age 20 who do not currently smoke. Randomly assign 50 of the 100 women to the smoking treatment and the other 50 to the no smoking treatment. Those in the smoking group smoke a pack a day for 10 years while those in the control group remain smoke free for 10 years.  Measure lung capacity for each of the 100 women.                                       Find 100 women age 30 of which 50 have been smoking a pack a day for 10 years while the other 50 have been smoke free for 10 years.  Measure lung capacity for each of the 100 women.  Analyze, interpret, and draw conclusions from data.
