Apr 15, 2015 · I was reading about normal approximation to binomial distribution and I dunno how it works for cases when you say for example p is equal to 0.3 where p is probability of …

Jul 16, 2018 · It is always a good idea to use a continuity correction when approximating binomial probabilities by normal ones. // There is a big difference between (b) in your original question …

Nov 24, 2013 · The Wikipedia Page has a good explanation and also have a look at the figure for CDF and the PDF which will give you some insight. Apart from that, the proof is actually (as an …

I'm reading about binomial distributions and I found this problem: We're trying to find the probability of finding 70-245 successes, given a population of 245 and a probability of success …

Apr 5, 2020 · Why are half-scale divisions used in continuity corrections for binomial approx to normal distribution? Why specifically half and not another correction?

You can use a normal approximation with her $\mu$ and $\sigma$ in the R statement 1 - pnorm(99.5, 125, 13.693) to get $0.9687,$ rounded to four places. Ordinarily, you cannot …

Nov 20, 2016 · Okay. So, many sources state different conditions for approximating binomial using normal. Variations I've seen are as follows. Assuming that we have Bin(n,p): 1. np and …

Binomial is discrete (ie- 0,1,2,3,4,5...), yet Normal is continuous (can take any decimal figure). Thus, we convert the discrete probability range to a continuous (and cut the missing space …
