    QUESTION ONE

    Solution:
    Hypotheses:
    H There is no difference between the mean annual rates of return between NYSE and NASDAQ, i.e.
    HA: The mean annual rates of return of big board is higher than that of NASDAQ, i.e.
    Test Statistic: t = follows a t-distribution with (n-1) degrees of freedom.
    Level of significance:
    Decision Rule: Reject the null hypothesis if p-value < alpha.
    Calculations:
    NYSE NASDAQ D
    17.16 15.8 1.36
    17.08 16.28 0.8
    15.51 16.21 -0.7
    8.43 17.97 -9.54
    25.15 7.77 17.38
    Mean D = 1.86
    SD = 9.730848
    t = =
    p-value = 0.345512
    Conclusion: Since p-value is greater than 10%, we do not reject the null hypothesis. Hence, there is insufficient evidence to conclude at 10% level of significance that the mean annual rates of return of big board are higher than that of NASDAQ.
