Discussion:
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.
State the Null Hypothesis and the Alternative Hypothesis.
Determine the test statistic.
Determine the P-value.
Make a decision regarding the hypotheses based on the P-value and the Level of Significance.
