Question

When you have the parental population that is highly skewed what sample size would you choose to make an accurate Xbar chart? Justify your answer based on the Central Limit Theorem (10 points).In this case, what is the relationship between the sample size and standard deviation (dispersion)?

Explanation / Answer

When the  population that is highly skewed, we would the sample size of at least 30 to make an accurate Xbar chart because by Central Limit Theorem for sample size of at least 30, no matter how the distribution of population is, sampling distribution will be always normally distributed.

Sample size and standard deviation are inversely related
