A) x-bar is approximately normally distributed.

B) The distribution of x-bar is uniform.

C) x-bar is normally distributed.

D) None of the above statements is true.

I am thinking it is uniformed because of the sample size of 32 which means if this was to be on a dotplot, there would only be one plotted data because the dice was rolled 32 times.

No. X-bar is the running mean. Each time a number is thrown, it changes the mean. It should approximate a normal distribution.
