Suppose the mean GPA of School A students is 3.5 and the standard deviation is 0.7 it is well known that this distribution is left-skewed. A random sample of n= 81 students will be drawn.

What is the sahpe of the sampling distribution of the random variable X(with a line over the top of x) which represents the sample mean of the 81 students who are selected.?

Left- skewed

right-skewed

approximately normal

we cannot determine this from the information given.
