WebThe distribution for z is the standard normal distribution; it has a mean of 0 and a standard deviation of 1. For Ha: p ≠ 26, the P-value would be P (z ≤ -1.83) + P (z ≥ 1.83) = 2 * P (z ≤ -1.83). Regardless of Ha, z = (p̂ - p0) / sqrt (p0 * (1 - p0) / n), where z gives the number of standard deviations p̂ is from p0.
