Suppose that in a large city the annual income is normally distributed with a standard deviation of $15,000. A real estate industry expert claims that the mean annual income of all real estate agents in the city is equal to $79,000. A sample of 30 real estate agents showed that their mean annual income was $84,230. Test the manager's claim using a level of significance of 0.05. What is your conclusion?
