WebVideo transcript. - [Tutor] What I wanna do in this video is give a primer, I'm thinking about when to use a z statistic versus a t statistic, when we are doing significance tests. So there's two major scenarios that we will see in an introductory statistics class, one is when we are dealing with proportions, so I'll write that on the left side ...
WebThe rule of thumb to use the normal approximation is that n*pi>5 and n (1-pi)>5. If pi=1%, then n must exceed 500. n=30 is not large enough. When n>30 or so the t and the z distribution are approximately equal and textbooks stop giving percentiles of the t distribution in the tables. • ( 6 votes) vokal9031 11 years ago don\u0027t be a menace happy birthday homieWebPerforming a Hypothesis Test Regarding the Difference Between Two Independent Means Step 1: State the null and alternative hypotheses.
