The weight of a product is normally distributed with a standard deviation of 0.4 KG. If the production manager wants no more than 19 percent of the products to weigh more than 5.2 KG, what should the average weight (u) be? = Hint: Find the z-value (from the normal distribution table) associated with the closest probability needed by the manager, then use this z-value to calculate the average weight. x-pl Remember, z=
