Suppose that a manager is interested in estimating the average amount of money customers spend in her store. After sampling 36 transactions at random, she found that the average amount spent was $37.85. She then computed a 99% confidence interval to be between $32.89 and $42.81. Which statement gives a valid interpretation of the interval? O There is a 99% chance that the mean amount spent by all customers is between $32.89 and $42.81. O The store manager is 99%...
