Consider taking a simple random sample from a large population. The SD of a sample proportion is √ p(1−p) n. p ( 1 − p) n. When np≥ 10 n p ≥ 10 and n(1−p)≥ 10, n ( 1 − p) ≥ 10, the sample proportion closely follows a normal distribution.
WebMar 13, 2024 · The sample proportion is p ^ = X / n where X ="the number of successes in the n trials" and n is the number of trials. If the outcome of each trial is B i, which takes the value 1 for a success and 0 otherwise then X = B 1 + B 2 +... + B n.
