According to a report in The New York Times, in the United States, loan officers earn an average of $67,960 a year and accountants earn an average of $70,130 a year. Suppose that these estimates are based on random sample of 1820 loan officers and 1650 accountants. Further assume the population standard deviations of the two groups are $21,700 and $22,540, respectively. Use a 2% level of significance to test the claim that the average salary of loan officers is less than that of accountants. STEP 1: Write the hypothesis statements, identify which hypothesis is the claim, and the type of test you need to complete (left-, right-, two-tail). State the level of significance. (5 points) STEP 2: Check the requirements. Calculate the appropriate standardized test statistic (two decimal places) and P-value (4 decimal places). Either show the formula you are using or state the calculator function. (8 points) STEP 3: Conclusion (make a decision) - your conclusion must include supporting evidence. (3 points) STEP 4; Complete the interpretation. (4 points)
