The distribution of sample means for that population will have a positively skewed distribution true or false?

If the original population has a positively skewed distribution, the distribution of sample means for that population, with N = 100 for each sample, will have a positively skewed distributionThe distribution of sample means for that population will have a positively skewed distribution true or false?
False if I remember the statistics correctly (I am writing from memory). The distribution of sample means is a normal distribution.The distribution of sample means for that population will have a positively skewed distribution true or false?
The One Who Knows is correct. It's the central limit theorem that states this. With such a large sample, the sample averages will be normal regardless of the population shape.
