If all possible samples of size n=30 are selected from a population with H=80 and o=10 and the mean is computed for each sample, then what 1 point shape is expected for the distribution of sample means? The sample means tend to form a normal-shaped distribution only if the population distribution is normal. The mean of each sample will be very close to 80, hence the distribution of means will have little variability. The sample size of n=30 is too small to predict the shape of the distribution.

Question
If all possible samples of size n=30 are selected from a population with u=80 and o=10 and the mean is computed for each sample, then what shape is expected for the distribution of sample means? The sample means tend to form a normal-shaped distribution only if the population distribution is normal. The mean of each sample will be very close to 80, hence the distribution of means will have little variability. The sample size of n-30 is too small to predict the shape of the distribution. The sample means tend to form a normal-shaped distribution whether the population is normal or not.
