Edexcel A Level Maths: 3.7 Hypothesis Testing with the Normal Distribution (Normal Approximation)

Pearson A level maths, applied year 2 textbook (3.7)

In this video I cover:

1. Approximating a binomial distribution using a normal approximation
2. Hypothesis testing with normal approximation
3. One tailed test
4. Two tailed test

loving these videos, really saving my stats for tuesday !! will you be doing a video on standardising the normal distribution/ coding?

[リオ利緒]

so when are you meant to convert the binomial distribution into the Y~N? like how do you know if you're meant to do that?

[liamcoghlan]

Your videos have been very helpful to me, thank you Zeeshan.

what's the difference between this topic of normal approximation and the binomial approximation?

[meronalsakat]

if you were null hypothesis, I would accept you

[ty-qoji]

Idk if this sounds dumb but how do you know to make the H0 and H1 with p and not mean. is it because the data in the first question is binomial.

[pokeninjaful]

Why don't we use rt(variance)^2/mean of X for the standard deviation

[liamcoghlan]

How do you know given the information in the questions that it is originally a binomial distribution?

[Ameera_]

so do we always take lower bound when we do the continuity correction?
