(b) Find the Pvalue. Round the answer to at least four decimal places. Cigarette Smoking A researcher found that a cigarette smoker smokes on average 29 cigarettes a day. She feels that this average is too low. She selected a random sample of 10 smokers and found that the mean number of cigarettes they smoked per day was 31. The sample standard deviation was 2.5. At a = 0.10, is there enough evidence to support her claim? Assume that the population is approximately normally distributed. Use the P-value method and a TI-83 Plus/TI- 84 Plus calculator. Part: 0 / 4 Part 1 of 4 (a) State the hypotheses and identify the claim. Ho (Choose one) H (Choose one) 0=0 This hypothesis test is a (Choose one) V test. X\f
