WINK, Inc. is made up of 450 employees who work a total of 13,500 hours per week. If the number of weekly work hours per person has a normal distribution and the standard deviation equals 7 hours, how many employees work more than 37 hours per week?______
选项
答案
72
解析
The correct answer is 72. Based on the given information, you know that the average is 13,500+450, or 30 hours. One standard deviation above the mean is 37 hours. The bell curve of a normal distribution puts the mean at 50%. One standard deviation in either direction is 34% away from the mean. So, one standard deviation is 84% of the employees. Since 84% of the employees work 37 hours, 16% work more than 37 hours. 16% of 450 employees = 72.
