We find S + = 15. Using the Binomial distribution function, we can find the p-value as P ( S + ≥ 15): P ( X ≥ 15) = ∑ i = 15 30 ( 30 i) ( 0.5) 30 − i ( 0.5) i = ∑ i = 15 30 ( 30 i) ( 0.5) 30 ≈ 0.5722322

WebOct 4, 2024 · Here are some real-life examples of Binomial distribution: Rolling a die: Probability of getting the number of six (6) (0, 1, 2, 3…50) while rolling a die 50 times; Here, the random variable X is the number of “successes” that is the number of times six occurs. The probability of getting a six is 1/6. WebMar 7, 2024 · It is a discrete distribution that is used in statistics that opposes a continuous distribution. The reason for this is that it only counts two states. That are represented as 0 (for failure) or 1 (for success) for a provided number of experiments. ...
