The mean hourly wage for employees in goods-producing industriesis currently $24.57 (Bureau of Labor Statistics website, April, 12,2012). Suppose we take a sample of employees from the manufacturingindustry to see if the mean hourly wage differs from the reportedmean of $24.57 for the goods-producing industries. a. State thenull hypotheses we should use to test whether the population meanhourly wage in the manufacturing industry differs from thepopulation mean hourly wage in the goods-producing industries. 1.2. 3. Choose correct answer from above choice State the alternativehypotheses we should use to test whether the population mean hourlywage in the manufacturing industry differs from the population meanhourly wage in the goods-producing industries. 1. 2. 3. Choosecorrect answer from above choice b. Suppose a sample of 30employees from the manufacturing industry showed a sample mean of$23.89 per hour. Assume a population standard deviation of $2.40per hour and compute the p-value. Round your answer to four decimalplaces. c. With = .05 as the level of significance, what is yourconclusion? p-value .05, H 0. We that the population mean hourlywage for manufacturing workers the population mean of $24.57 forthe goods-producing industries. d. Repeat the preceding hypothesistest using the critical value approach. Round your answer to twodecimal places. Enter negative values as negative numbers. z = ; H0
