Suppose you are interested in buying shares of a stock. You compute the returns (%) on that stock using the stock prices available for the previous months to test whether the average return on this stock exceeds 5. We have n = 50, X = 8.25, 0 = 10.50, Skewness = 1.12, Excess Kurtosis = 1.85 (Marks 12) 1. The distribution of returns is normal 2 The null hypothesis is Ho : / a 9. Given the observed value of the test statistic, we decide to reject the null
