... If we did not have a computer that could calculate Binomial probabilities, we could use a normal approximation. Under the null hypothesis, the random variable X has approximately a√normal distribution, with mean = µ X = np0 = 114.3 and standard deviation σ X = np0 (1 − p0 ) = 10.3. Remark. It is a g ...
