The average weight of a set X of 100 bags of rice is 90 pounds , and the standard deviation is 8 pounds. Bag A weighs 2 standard deviations below the average weight and Bag B weighs 5 pounds more than Average.
Choose if quantity A or quantity B is bigger , equal or the information provided is not sufficient:
Quantity A: Difference between weight of Bag A and Bag B Quantity B: The range of weight of bags in set X
Hint:
Without knowing how the data are distributed, how can we determine the range (to calculate quantity B) just from knowing the mean and standard deviation?
So, I feel the answer should be: Cannot be determined.
