WebAug 6, 2024 · Briefly, the question asked is "out of 900 trials, we have 490 heads - is the coin biased?" p-value: binomial: 0.008468 p-value: normal approximation: 0.0078 p … WebThe mean of the binomial distribution is n p. In our case, n is the number of tosses in each trial, and p=0.5 is the chance of a coin landing heads up. So the mean of 1000 tosses is 500, as expected. The variance of a binomial distribution is n p (1 - p). So the standard deviation (in our case) is the square root of n, divided by 2.
WebNext, consider if we thought the coin was biased in favor of tails. \[H_O: p=0.50\] \[H_A: p<0.50\] ... the sample size is sufficient to use the normal approximation to the binomial; Checking the first two conditions involves judging whether or not the sampling was done in a random and independent fashion. The third condition can be judged ... WebYou can test a binomial distribution against a specific probability using the exact binomial test. x = the number of successes; n = the number of trials; p = hypothesised probability of success; Here we can test a series of 10 coin flips from a fair coin and a biased coin against the hypothesised probability of 0.5 (even odds).

So we calculate that probability as: Pr ( X = 560) = ( 1000 560) 0.5 560 ( 1 − 0.5) 1000 − 560 ≈ 0.00002.
