How do you find p in statistics
WebMar 13, 2024 · There are several steps you can take in order to find the p-value: 1) First, you need to state your null and alternative hypotheses. The null hypothesis is usually stated as … Web1 Answer. Sorted by: 1. a) is correct. b) The problem is that the formula for the minimum required sample size is. n = z 2 ⋅ p ⋅ ( 1 − p) d 2. where z = z α / 2 and d is half the length of the corresponding confidence interval. So in order to determine n you need to know the true value of p, which is what you want to estimate.

WebJan 5, 2024 · The way we calculate this probability depends on whether or not events A and B are mutually exclusive or not. Two events are mutually exclusive if they cannot occur at the same time. If A and B are mutually exclusive, then the formula we use to calculate P(A∪B) is: Mutually Exclusive Events: P(A∪B) = P(A) + P(B) WebThen the next step is we calculate a p-value. And the p-value, which stands for probability value, is the probability of getting a statistic at least this far away from the mean if we …
