Quit smoking: the new england journal of medicine published the results of a double-blind, placebo-controlled experiment to study the effect of nicotine patches and the antidepressant bupropion on quitting smoking. the target for quitting smoking was the 8th day of the experiment. in this experiment researchers randomly assigned smokers to treatments. we conducted a hypothesis test to determine if the side effect rates are significantly different for nicotine patches versus bupropion at a 5% level of significance. (the normality conditions are met by the data.) the p-value is 0.04. what does a p-value of 0.04 mean?

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
