Standard and Poor 500 (S&P500) is an index of 500 large corporations capitalization on the NYSE. The annual rate of return of the index is approximately normal. From January 1, 1960 to December 31, 2019, the S&P 500 had an average annual return of 10.98%, with a deviation standard of approximately 17.46%. Consider this normal distribution to be the distribution of annual returns over a long period. (a) In what mean interval do 95% of the annual returns fall? (95% center) (b) Stock prices can go up or down. What are the yields of 2.5% lower?
