郭同学题干见图片 Q. Based on the results of the regression model shown in Exhibit 2, the best conclusion Garfield can make about a hypothesis that the coefficient JPY/USD change is zero is to: A)reject the alternative hypothesis. B)reject the null hypothesis. C)fail to reject the null hypothesis 这题我选择的是B，答案是C。JPY/USD change这个字段的t检验值和pvalue都不算大啊，这个怎么能fail to reject呢

Vincent同学你好，P-value已经很大了， P=0.33， 假设显著性水平是0.05, 那么P>0.05, fail to reject.
