A survey of 1200 adult males finds that 412 have a high school diploma (but no more education). From among those in the sample with high school diplomas, the mean annual income is $28,740 with a standard deviation of $4,270. Among the sample of workers without high school diplomas, the mean income is $22,600 with a standard deviation of $5,400. Use a hypothesis test to determine if annual income among individuals who complete high school is significantly larger than those who do not. Include all steps in your analysis.
