Español Cigarette Smoking A researcher found that a cigarette smoker smokes on average 30 cigarettes a day. She feels that this average is too low. She selected a random sample of 9 smokers and found that the mean number of cigarettes they smoked per day was 32. The sample standard deviation was 2.4. At a =0.10, is there enough evidence to support her claim? Assume that the population is approximately normally distributed. Use the critical value method and tables. do Part 1 of 5 (a) State the hypotheses and identify the claim. Ho: (Choose one) ▼ ロ<ロ H : (Choose one) ▼ ロ=ロ ロロ This hypothesis test is a (Choose one) test. Part 2 of 5 (b) Find the critical value(s). Round the answer to three decimal places. If there is more than one critical value, seperate them with commas. Critical value(s): Part 3 of 5 (c) Compute the test value. Always round t score values to three decimal places.
