The distribution of actual weights of 8-ounce chocolate bars is approximately normal with a mean of 8.1 ounces and a standard deviation of 0.1 ounces. 1 ne company who produces the chocolate bars does not want the weight to fall below 7.85 ounces, for fear that consumers will complain. b) Suppose you select 4 chocolate bars at random and calculate the mean weight. What is the probability that the mean weight of 4 randomly selected chocolate bars is less than 7.85 ounces. Be sure to: • draw, label, and shade the distribution verify conditions for shape and independence and show work for mean and standard deviation of this distribution standardize find the area give answer in context
