Can binomial distribution be normal
WebApr 3, 2024 · I googled and found that if n approaches infinity and p and q are large (not close to either 1 or 0) then it follows a normal distribution. But if p is large np should also be infinite. So it seems to me that normal distribution can only approximate the binomial distribution when n, p, and q all are finite. WebJul 7, 2024 · A normal distribution with mean 25 and standard deviation of 4.33 will work to approximate this binomial distribution. When Is the Approximation Appropriate? By using some mathematics it can be …

Compute the pdf …
WebNov 6, 2024 · Calculating the p-value by normal approximation. When the sample size is large, binomial distributions can be approximated by a normal distribution. To build the normal distribution, I need mean and standard deviation. I can calculate this from the horror movie data. sample_mean is 92.7 sample_sd is 89.64 WebMar 17, 2024 · The binomial distribution involves a discrete random variable. Probabilities in a binomial setting can be calculated in a straightforward way by using the formula for a binomial coefficient. While in theory, this is an easy calculation, in practice it can become quite tedious or even computationally impossible to calculate binomial …
WebDec 6, 2024 · I don't think you can conclude that N(p,p(1−p)) could represent an approximation of bernoulli(p). First of all, for a bernoulli variable, a random sample could only be 0 or 1, on the other hand, the range of normal variable could be from -inf to inf. Secondly, If we have a random distribution with mean p, and variance p(1-p), once we … WebJan 11, 2024 · The binomial distribution with probability of success p is nearly normal when the sample size n is sufficiently large that np and n(1 − p) are both at least 10. The …
