Age and smoking data were gathered and are summarized here (change the tab on the sheet to problem 4). Perform a hypothesis test at the 5% significance level to see if there is correlation between the current age of the smoker and the number of cigarettes smoked per day. See the homework or textbook for an appropriate outline of a hypothesis test.

a) If correlation is found answer the following: Is the correlation positive or negative, what does that mean for smokers? What is the equation of the regression equation. If I were 50 and smoking about how many cigarettes would I be expected to have?

b) If no correlation is found simply state that no correlation is found and take a moment to hypothesize why there is no correlation.
