Q: A national survey of restaurant employees found that 75% said work stress had a negative impact on their personal lives. A sample of 100 employees from a popular restaurant chain finds that 68 answer "Yes" when asked, "Does work stress have a negative impact on you personal life?" Is there a eason to believe the restaurant chain's employees differ from the national percentage of 75%? Use a level of significance of 5%, and clearly show the five traditional hypothesis testing steps.
