The mean hourly wage for employees in goods-producing industries is currently $24.57 (bureau of labor statistics website, april, 12, 2012). suppose we take a sample of employees from the manufacturing industry to see if the mean hourly wage differs from the reported mean of $24.57 for the goods-producing industries. suppose a sample of 30 employees from the manufacturing industry showed a sample mean of $23.89 per hour. assume a population standard deviation of $2.40 per hour. use latex: \alphaα = 0.05 as the level of significance. what is your conclusion? d. repeat the preceding hypothesis test using the critical value approach.
