(8 points) A nationwide survey of working adults indicates that only 50% of them are satisfied with their jobs. The president of a large company believes that more than 50% of employees at his company are satisfied with their jobs. To test his belief, he surveys a random sample of 100 employees, and 54 of them report that they are satisfied with their jobs. Can he conclude that more than 50% of employees at the company are satisfied with their jobs? Use the α = 0.05 level of significance. State: Write the null and alternative hypotheses and label all given values with appropriate notation. Plan: 1. Is it a simple random sample? 2. Is our population size large enough so that our sample is independent? 3. Can we use a normal distribution with our sample? Do: Find z-score and P-value using a calculator or chart. What is the result? Conclude: Interpret your result in the context of the problem
