C. Compute the test value D. Make a decision
Cigarette Smoking A researcher found that a cigarette smoker smokes on average 33 cigarettes a day. She feels that this average is too high. She selected a
random sample of 10 smokers and found that the mean number of cigarettes they smoked per day was 27. The sample standard deviation was 2.5. At a=0.01,
is there enough evidence to support her claim? Assume that the population is approximately normally distributed. Use the critical value method and tables.
