A researcher wants to determine the impact that smoking has on resting heart rate. She randomly selects 7 people from 3 groups and obtains the heart rate data (beats per minute) in the table. Complete parts (a) through (c). Nonsmokers 51 76 Light Smokers Heavy Smokers 73 50 56 80 48 66 63 64 70 81 69 63 76 57 45 72 60 77 74 (a) Test the null hypothesis that the mean resting heart rate for each category is the same at the = 0.05 level of significance. Note that the requirements for a one-way ANOVA are satisfied. Identify the null and alternative hypotheses. OA. Ho Hns His #hs H: Hns His Phs = OB. Ho Hns His Phs H: Hns His Hhs = C. Ho Hns His Phs H: At least one of the means is different. Identify the P-value. P-value=0.004 (Round to three decimal places as needed.)
