Answer #1

JB Test statistic can be calculated as below

N/6(S^2+(K)^2/4)

N=801 , S=0.188, K=0.605

JB test statistic is (801/6)(0.188^2+(-2.395)^2/4)=16.94

According to ciritical table used by JB we have critical value for 5% significance level equals to 5.991 hence test statistic is greater than critical value

Therefore we can reject the null that sample of residuals is normal

Option C is correc t

    Imagine that you regressed the earnings of individuals on a constant, a binary variable (“Male”) which takes on the value of 1 for males and is 0 otherwise, and another binary variable (“Female”) which takes on the value of 1 for female and is 0 otherwise. Because females typically earn less than males, you would expect: Group of answer choices autocorrelation or serial correlation to be a serious problem. the estimated coefficient for Male to have a positive sign, and...
