State whether the standardized test statistic t indicates that you should reject the null hypothesis. Explain. (a) t= 1.868 (b) t = 0 (c) t= - 1.772 (d) t= - 1.865 to = - 1.782 (a) For t= 1.868, should you reject or fail to reject the null hypothesis? O A. Fail to reject Ho, because t - 1.782. O D. Fail to reject Ho, because t> - 1.782. (b) For t= 0, should you reject or fail to reject the null hypothesis? O A. Reject Ho, because t> - 1.782. O B. Reject Ho, because t - 1.782. (c) Fort= - 1.772, should you reject or fail to reject the null hypothesis? O A. Fail to reject Ho, because t> - 1.782. O B. Fail to reject Ho, because t - 1.782. O D. Reject Ho, because t
