Whenever the population has a normal probability distribution, the sampling distribution of is a normal probability distribution for?

If sample size was 1, the distribution of the sample means would be identical to the population distribution, regardless of the type of distribution. In this case, its already normal. The larger the sample size, the more normal it becomes if it wasn't already.

I hope this helped!

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )
