Because the sample size is​ 9, do you need to be concerned about the shape of the population distribution when conducting the t test in​ (a)? Explain. Choose the correct answer below. A. With a small sample​ size, it is difficult to evaluate the assumption of a skewed distribution.​ However, the distribution may be asymmetric because the mean and the median are not close in value. B. With a small sample​ size, it is difficult to evaluate the assumption that the distribution follows the​ Student's t distribution.​ However, the distribution may be symmetric because the mean and the median are close in value. C. With a small sample​ size, it is difficult to evaluate the assumption of normality.​ However, the distribution may be symmetric because the mean and the median are close in value.
