Question: According to the National Institute for Occupational Safety and Health, job stress poses a

major threat to the health of workers. A national survey of restaurant employees found that

75% said that job stress had a negative impact on their personal lives. A sample of 100

employees of a restaurant chain finds that 68 answer “Yes” when asked: “Does job stress

have a negative impact on your personal life?” Is this good reason to think that the proportion

of all employees of this chain who would say “Yes” differs from the national proportion,

p₀ = 0.75? Use a 5% level of significance.
