Clgarette 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 \( P \)-value method and tables. Part: \( 0 / 5 \) Part 1 of 5 (o) State the hypotheses and identify the claim.
