In 42 of the 66 years from 1950 through 2010 (in 2011 there was virtually no change), the S&P 500 finished higher after the first five days of trading. In 37 out of 42 years, the S&P 500 finished higher tor the year. Is a good first week a good omen for the upcoming year? The following table gives the firsts week and annual performance over this 66-year period: a. If a year is selected at random. What is the probability that S&P 500 finished higher for the year? b. Given that the S&P 500 finished higher after the first his days of trading what is probability that it finished higher for the year? c. Are the two events “first week performance" and “annual performance" independent? Explain. d. Look up the performance after the five days of 2017 and the 2017 annual performance of the S&P 500 at finance yahoo.Com. Comment on the results.
