A neurologist is testing the effect of a drug on response time by injecting 100 rats with a unit does of the drug, subjecting ea
ch to neurological stimulus and recording its response time. The neurologist knows that the mean response time for rats not injected with the drug is 1.2 seconds. The mean of the 100 injected rats response times is 1.05 seconds with a sample standard deviation of 0.5 seconds. Do you think that the drug has an effect on response time?
Cutting down on your consumption of nicotine over time until eventually your consumption is non-existent. if you quit cold turkey, you will go through withdrawals. Not fun.
