NO.PZ2017092702000162问题如下The following table shows the sample correlations between the monthly returns for four fferent mutufun anthe S P 500. The correlations are baseon 36 monthly observations. The fun are follows: Test the null hypothesis theaof these correlations, invially, is equto zero against the alternative hypothesis thit is not equto zero. Use a 5 percent significanlevel. The critict-value for n − 2 = 34 , using a 5 percent significanlevel ana two-tailetest, is 2.032. First, take the smallest correlation in the table, the correlation between Fun3 anFun4, ansee if it is significantly fferent from zero. Accong to the formula of correlaion t-test, its calculatet-value is t=1.903. This correlation is not significantly fferent from zero. If we take the next lowest correlation, between Fun2 anFun3, this correlation of 0.4156 ha calculatet-value of 2.664. So this correlation is significantly fferent from zero the 5 percent level of significance. All of the other correlations in the table (besis the 0.3102) are greater th0.4156, so they too are significantly fferent from zero.这题不是N=34吗？大于30呀，5%的significant 不是等于正负1.96吗？
