When retuins from a project can be assumed to be normally distributed, such as those shown in Figure 13 - 6 (represented by a symmetrical, bell-shaped curve), the areas under the curve can be determined from statistical tables based on standard deviations. For example, 6826 percent of the distribution will fall within one standard deviation of the expected value ( D ) 10 ). Similarly, 95.44 percent will fall within two standard deviations (D20), and so on. An abbrevlated table of areas under the normal curve is shown next. Assume Project A has an expected vatue of $24.000 and a standard deviation (d) of $4,800 a, Whot is the probsbitity that the outcome with be between $16,800 and $31,200 ? Note: Do not round intermediate calculations. Round your answer to 4 decimal places. b. What is the probability that the outcome will be between $14,400 and $33,600 ? Note: Do not round intermediate calculations. Round your answer to 4 decimal places. c. What is the probability that the outcome will be at loost 514,400 ? Notel Do not round intermediate calculations. Round your answer to 4 decimal places. b. What is the probability that the outcome will be between $14,400 and $33,600 ? Note: Do not round intermediate calculations. Round your answer to 4 decimal places. c. What is the probablity that the outcome will be at least $14,400 ? Note: Do not round intermediate calculations. Round your answer to 4 decimal places. d. What is the probablity that the outcome will be less than $31,900 ? Note: Do not round intermediate calculations. Round your answer to 4 decimal places. e. What is the probability that the outcome will be less than $19,200 or greater than $26,400 ?
