Question

Which one of these is a false statement about a simple random sample is drawn from a population ???

The sample mean has a normal distribution regardless of the sample size if the population is normally distributed.
The mean of the sample means gets closer to the population mean as the sample size increases.
The standard deviation of sample means decreases as the sample size increases.
The sample mean is distributed approximately normal if the sample size is sufficiently large (30 or more).

or NONE OF THE ABOVE?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
