Customer Question

I need this assignment completed. Calculate the return on equity (ROE) for a sample of 20 banks for the year before the Sarbanes-Oxley Act was enacted. For the same sample of banks, calculate the ROE for the year following the enactment of the Sarbanes-Oxley Act.
Later, answer the following questions:
After the enactment of the Sarbanes-Oxley Act, was the average bank’s ROE lower than it was before the act? If so, why do you think that was the case?
What is the null hypothesis for this hypothesis test?
What is the alternative hypothesis for this hypothesis test?
Choose at least three different significant levels to conduct the hypothesis test. Is it possible that a Type I error occurred with the hypothesis test? Why or why not?
Is it possible that a Type II error occurred? Why or why not?
Submit your answers in an eight- to ten-page Word document.
