Suppose that a national survey finds that 73 percent of restaurant employees say that work stress has a negative impact on their personal lives. A random sample of 200 employees of a large restaurant chain finds that I4l employees say that work stress has a negative impact on their personal lives. Formulate the null and alternative hypotheses needed to attempt to provide evidence that the percentage of work-stressed employees for the restaurant chain differs from the national percentage. Use critical values and a p-value to perform the hypothesis test by setting a equal to .10, .05, .01, and .001.
