text: need help with stats final!!? the weight of a randomly selcted can of a new soft drink is known to have a normal distribution with a mean of 8.3 oz and a standard deviation of 0.2 oz. the weight that should be stamped on the can so that only 2% of cans are underweight is a. 7.89 oz. b. 8.71 oz. c. 8.26 oz. d. 8.28 oz.  thanks in advance for the help ok, this is the thought process you need to use.  we want not more than 2% of the cans underweight.  most of 'em are going to be above 2 standard deviations below the mean; figure, 8.3-0.4 = 7.9  ok, my computation is pretty close to a; that reflects my using round digits rather than the exact z value you need.
