For a sampling distribution to be approximately normally distributed, we need that the underlying population distribution is also approximately normally distributed.
True
False

False
It is not necessary for the population of data to be normally distributed for the sampling distribution to have an approximate normal distribution. If the sample size is high (generally greater than 30), from the Central Limit Theorem the sampling distribution will have an approximately normal distribution even if the population is not normally distributed
