Naturally, the weights of individual bars vary somewhat. Suppose that the weights of these candy bars vary according to a normal distribution with mean u = 2.2 ounces and standard deviation o= 0.04 ounces. a. What proportion of candy bars weigh less than the advertised weight? b. What proportion of candy bars weigh more than 2.25 ounces? c. What proportion of candy bars weigh between 2.2 and 2.3 ounces? d. If the manufacturer wants to adjust the production process so that only 1 candy bar in 1000 weighs less than the advertised weight, what should the mean of the actual weights be (assuming that the standard deviation of the weights remains 0.04 ounces)? that weights of
