A study used nicotine gum to help people quit smoking. It was recorded whether each participant had a cigarette after 28 days of the study. The results showed that 174 out of 1649 people using a nicotine gum succeeded, and 66 out of those who took a placebo (also a sample of 1649) succeeded in quitting. a) Find the proportion of people using nicotine gum that stopped smoking (p1-hat)and the proportion of people using the placebo that stopped smoking (p2-hat).  b) use your calculator to run a two-proportion hypothesis test. Use your p-value to state the conclusion in the context of the problem. (As part of your answer, write what you typed into your calculator.)
