For 30 randomly selected Rolling Stones concerts the mean gross earnings is 2:59 million dollars. Assuming a population
standard deviation gross earnings of 0.51 million dollars, obtain a 95%
confidence interval for the mean gross earnings of all Rolling Stones
concerts (in millions). Interpret this confidence interval.
