A stockbroker who wants to compare mean returns and risk (measured by variance) of two stocks and gets the following results:
First stock                           Second stock
N1 = 31 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â N2 = 31
1 = 0.45Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
2 = 0.35
S1 = 0.60 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â S2 = 0.40
Are there any significant differences in the mean returns and risks? (Assume that daily price changes are normally distributed.)
