Chapter 10.4, Problem 53E
Job Satisfaction According to a 2016 study conducted by the Society for Human Resources Management, 38% of U.S. employees reported being very satisfied with their job. In the same study, 51 % indicated they are satisfied but to a lesser degree. If 200 employees are selected at random, calculate the following. (See Example 6.) (Data from: www.shrm.org.)
The probability that between 70 and 80 employees are very satisfied
