Rock band The Rolling Stones have played scores of concerts in the last twenty years. For 30 randomly selectedRolling Stones concerts, the mean gross earnings is 2.2 million dollars.Part a) Assuming a population standard deviation gross earnings of 0.51 million dollars, obtain a 99% confidenceinterval for the mean gross earnings of all Rolling Stones concerts (in millions). Please carry at least three decimalplaces in intermediate steps. Give your answer to the nearest 3 decimal places.Confidence interval:Part b)Which of the following is the correct interpretation for your answer in part (a)?A. There is a 99% chance that the mean gross earnings of all Rolling Stones concerts lies in the intervalB. If we repeat the study many times, 99% of the calculated confidence intervals will contain the mean gross earning of all Rolling Stonesconcerts.C. We can be 99% confident that the mean gross earnings for this sample of 30 Rolling Stones concerts lies in the intervalD. None of the above

ASK YOUR TEACHER At Burnt Mesa Pueblo, archaeological studies have used the method of tree-ring dating in an effort to determine when prehistoric people lived in the pueblo. Wood from several excavations gave a mean of (year) 1230 with a standard deviation of 30 years. The distribution of dates was more or less mound-shaped and symmetric about the mean. Use the empirical rule to estimate the following. (a) a range of years centered about the mean in which about 68% of the data (tree-ring dates) will be found between and A.D. (b) a range of years centered about the mean in which about 95% of the data (tree-ring dates) will be found between and A.D. (c) a range of years centered about the mean in which almost all the data (tree-ring dates) will be found between and A.D. MY NOTES

You may need to use the appropriate appendix table or technology to answer this question. Money reports that the average annual cost of the first year of owning and caring for a large dog in 2017 is $1,448. The Irish Red and White Setter Association of America has requested a study to estimate the annual first-year cost for owners of this breed. A sample of 50 will be used.
