As sample size increases, the size of the t-statistic gets larger, and the likeilhood of rejecting the null hypothesis Increases B. As sample size increases, the size of t-statistic gets smaller, and the likelihood of rejecting the nil hypothesis OC. As sample variance decreases, the size of the t-statistic gets farger, and the likelithood of rejecting the null hypothesis D. As sample variance decreases, the size of the t-statistic gets smaller, and the likelihood of rejecting the null hypothesis ?E,Both A &C; are correct F. Both B& D are correct Save 4 MacBook Pro F6 F7 F8 Fm

Explanation / Answer

Both A and C are correct . Increasing n will result in a sample mean closer to the population mean but only in the case when sample mean is not different from population. So when n is high x bar still differs from u which leads to rejection of null hypothesis. And bigger sample size will decrease the variance .
