题目
An analyst regresses the returns of 60 stocks in a stock market and finds that the best fitting line is:Return=8% +9%×BetaIf the standard error of the estimate is 6% and the standard error of the coefficient of Beta is 4%, the test statistic for the coefficient is closest to:
选项
A.1.33
B.1.43
C.1.50
D.2.25
答案
D
解析
The null hypothesis for this test is that the coefficient is equal to zero. Therefore the test statistic = (9% - 0)/4%=2.25.该检验的零假设是系数等于零。 因此测试统计=(9% - 0)/4%=2.25
