The means are not equal and the standard deviation of the sampling distribution is smaller O B. The means are not equal and the standard deviation of the sampling distribution is larger O C. The means are equal but the standard deviation of the sampling distribution is langer OD. The means are equal but the standard deviation of the sampling distribution is smaller The means and standard deviations are equal OE
