A firms marketing manager believes that total sales for the firm next year can be modeled by using a normal distribution with a mean of 2.5 million and a standard deviation of 300,000. What is the probability that the firms sales will exceed 3 million? What is the probability that the firms sales will fall within 150,000 of the expected level of sales? In order to cover fixed costs, the firms sales must exceed the break-even level of 1.8 million. What is the probability that sales will exceed the break-even level? Determine the sales level that has only a 9% chance of being exceeded next year.
