A large software development firm recently relocated its facilities. Top management is interested in fostering good relations with their new local community and has encouraged their professional employees to engage in local service activities. They believe that the firm's professionals volunteer an average of more than 15 hours per month. If this is not the case, they will institute an incentive program to increase community involvement. A random sample of 24 professionals reported a sample mean of 16.6 hours and a standard deviation of 2.22 hours. At Alpha = 0.05,

		we reject the alternative hypothesis
		we fail to reject the null hypothesis
		the firm should institute an incentive program because there is evidence indicating that professional employees volunteer less than 15 hours per month on average.
