Which of the following control charts doesn’t work based on the central limit theorem?
- A. u chart B. p chart C. X̅ chart D. X chart
Homework Answers
Answer:
D. X chart
Explanation:
We know that the central limit theorem is based on the average values or statistic of independent samples. The u chart, p chart, and X-bar chart are based on the average values or statistic of samples, so these are work based on the central limit theorem, but X chart is the chart of individual observations which does not depends on the average values or statistic of sample, so central limit theorem does not work in this case.

2. Evaluate the following statement. To answer this question please state the Central Limit Theorem and explain why central limit theorem is so important. The samples mean of a random sample of n observations from a normal population with mean u and variance o2 is a sampling statistics. The sample mean is normally distributed with mean u and variance oʻ/n due to central limit theorem.
