Cigarette Smoking A researcher found that a cigarette smoker smokes on average 34 cigarettes a day. She feels that this average is too high. She selected a random sample of 11 smokers and found that the mean number of clgarettes they smoked per day was 28. The sample standard deviation was 2.6. 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. Part: \( 0 / 5 \) Part 1 of 5 (a) State the hypotheses and identify the claim.
(a) State the hypotheses and identify the claim. \[ \begin{array}{l} H_{0}: \\ H_{1}: \end{array} \] This hypothesis test is a test.
