Rock band The Rolling Stones have played scores of concerts in the last twenty years. For 30 randomly selected Rolling Stones concerts, the mean gross earnings is 2.59 million dollars.Part a) Assuming a population standard deviation gross earnings of 0.49 million dollars, obtain a 99% confidence interval for the mean gross earnings of all Rolling Stones concerts (in millions).Confidence interval: (Part b)Which of the following is the correct interpretation for your answer in part (a)?A. We can be 99% confident that the mean gross earnings for this sample of 30 Rolling Stones concerts lies in the intervalB. There is a 99% chance that the mean gross earnings of all Rolling Stones concerts lies in the intervalC. If we repeat the study many times, 99% of the calculated confidence intervals will contain the mean gross earning of all Rolling Stones concerts.OD. None of the above

Active Learning vs Passive Learning: Feelings of Learning? After the active learning or passive learning class, students rated the extent to which they agreed with the statement “I feel like I learned a great deal from this class.” Ratings were on a 5-point scale with greater numbers indicating greater agreement. For the 142 students in the active learning environment, the mean rating was 3.338 with a standard deviation of 0.922. For the 154 students in the passive learning lecture, the mean rating was 3.753 with a standard deviation of 0.873. Test whether ratings on feelings of learning are significantly lower, on average, with active learning. (Let Group 1 represent active learning and Group 2 represent passive learning.)

Question: Part B. Construct a 95% confidence interval of the mean pulse rate for adult males. __bpm <u<__bpm Multiple Choice: Compare the results. A. The confidence intervals do not overlap, so it appears that adult females have a significantly higher mean pulse rate than adult males. B. The confidence intervals overlap, so it appears that adult males have a significantly higher mean pulse rate than adult females. C. The confidence intervals do not overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males. D. The confidence intervals overlap, so it appears that there is no significant difference in mean pulse rates between adult females and adult males.
