Question 24 of 25 This test: 100 point(s) possible This question: 5 point(s) possible Submit test A cruise company would like to estimate the average beer consumption to plan its beer inventory levels on future seven-day cruises. (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 bottles . (Round to the nearest whole numbers.) b. What assumptions need to be made about this population? O A. The only assumption needed is that the population distribution is skewed to one side. O B. The only assumption needed is that the population follows the normal probability distribution. O C. The only assumption needed is that the population size is larger than 30. O D. The only assumption needed is that the population follows the Student's t-distribution. ourc Ions
