*** Watch Video and … ***
Please watch this short video (right click and “open link in new window” if necessary) by JBStatistics.
In this video, JBStatistics mentions that “Some sources say: If n > 30 use a Z test”, but then he mentions that he wants you to “forget that you heard such a thing”.
Please thoroughly explain why you would want to ignore/follow the rule “If n > 30 use a Z test”.
