In a study of smokers who tried to quit smoking

Exercise Number 2

In a study of smokers who tried to quit smoking with nicotine patch therapy, 39 were smoking one year after the treatment, and 32 were not smoking one year after the treatment. We want to use a .05 significance level to test the claim that among smokers who try to quit with nicotine patch therapy, the majority are smoking a year after the treatment

• The null hypothesis is The alternative hypothesis is
• The value of the standard score for sample proportion is
• The Critical Value is
• The P Value is
• I conclude that based on the data presented above,
• A type 1 error for this test is that we would reject the fact that 32 patients were smoke free one year after the treatment when they were.
• A type 2 error for this test is that we would accept the 32 patients were smoke free one year after the treatment when they were not.
• The P value if the claim is modified to state that the proportion is equal to .5.
