Question

The following is an excerpt from this same study. 'A total of 311 subjects (34.8%) discontinued one or both medications. Seventy-nine subjects stopped treatment because of adverse events: 6 in the placebo group (3.8%), 16 in the nicotine patch group (6.6%), 29 in the bupropion group (11.9%), and 28 in the combined treatment group (11.4%). The most common adverse events were insomnia and headache. "Recall that 160 smokers took the placebo and 244 smokers used nicotine patches. Could the researcher use this data with a Module 8 inference procedure to test a claim about (or to estimate the difference in) side effects from a placebo compared to nicotine patches? 0 0 Yes, because subjects were randomly assigned to treatment groups (1) Yes, the percentages of side effects are large enough to see a difference (iii) No, the conditions for use of a normal model for the sampling distribution of sample differences are not met. (iv) No, the experiment did not randomly assign side-effects to subjects.

Answer 1

The answer is No, the conditions for use of a normal model for the sampling distribution of sample differences are not met.
