(The ship certainly doesn't want to run out of beer in the middle of the ocean!) The average beer consumption over 21 randomly selected seven-day cruises was 81 ,588 bottles with a sample standard deviation of 4,518 bottles. Complete parts a and b below. a. Construct a 99% confidence interval to estimate the average beer consumption per cruise. The 99% confidence interval to estimate the average beer consumption per cruise is from a lower limit of bottles to an upper limit of C] bottles. (Round to the nearest whole numbers.) b. What assumptions need to be made about this population? :ents esource e Resour Options lication To The only assumption needed is that the population distribution is skewed to one side. The only assumption needed is that the population follows the normal probability distribution. The only assumption needed is that the population size is larger than 30. The only assumption needed is that the population follows the Student's t-distribution. @ Time Remaining: 02:16:08 Next
