A study was conducted to compare the resting pulse rates (in beats per minute, BPM) of smokers to non-smokers. The difference in BPM was measured as smokers - nonsmokers. The 95% confidence interval of the difference in mean BPM was: -3.3 BPM < [u (smoke) – u (nonsmoke)] <10.9 BPM. < Based on this information, answer the following questions: 1. Did the smokers and non-smokers have significantly different mean BPMs? [ Select] 2. Who had the higher mean BPM in the sample? [ Select ] 3. If you had run the hypothesis test on this data, what would you have concluded? [Select ] 4. If you had run the hypothesis test on this data, what would your p-value have been? | [ Select]
