The average starting salary of students who graduated from colleges of Business in 2009 was $48,400. A sample of 100graduates of 2010 showed an average starting salary of $50,000. Assume the standard deviation of the population is known to be $8000. We want to determine whether or not there has been a significant increase in the starting salaries. Step 1. Statement of the hypothesis Step 2. Standardised test statistic formula Step 3. State the level of significance Step 4. Decision Rule (Draw a bell to show rejection zone) Step 5. Calculation of the statistic Step 6. Conclusion
