With samples of 30 or more individuals, the approximation of the distribution of means will be:
A)a bimodal distribution
B)a rectangular distribution
C)a normal curve
D)the distribution of Z scores

Question

Quizplus · Accepted Answer

As per the Central Limit Theorem, with a sample size of 30 or more, the distribution of means will approximate a normal curve, regardless of the shape of the population distribution. This is because the means of larger samples tend to follow a normal distribution, regardless of the shape of the underlying distribution. Thus, a normal curve is the best approximation for the distribution of means with a sample size of 30 or more individuals.
