For 30 randomly selected Rolling Stones concerts, the mean gross earnings is $2.27 million.  Assuming a population standard deviation gross earnings of $0.5 million, obtain a 99% confidence interval for the mean gross earnings of all Rolling Stones concerts.  Interpret your answer in words. (A)  Calculate α and z_(α/2)         (B)  Calculate z_(α/2)∙σ/√n           (C)  Calculate the 99% confidence interval   (D)  Interpret your results

Find the z critical value associated with 85% confidence.

You are interested in estimating the the mean weight of the local adult population of female white-tailed deer (doe). From past data, you estimate that the standard deviation of all adult female white-tailed deer in this region to be 29 pounds. What sample size would you need to in order to estimate the mean weight of all female white-tailed deer, with a 96% confidence level, to within 8 pounds of the actual weight? (Use Excel to find the appropriate critical value and round to 3 decimal places.)Sample Size:
