WebAug 16, 2010 · I like the survival function (upper tail probability) of the normal distribution a bit better, because the function name is more informative: p_values = scipy.stats.norm.sf(abs(z_scores)) #one-sided p_values = scipy.stats.norm.sf(abs(z_scores))*2 #twosided 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. ( 4 votes) tahseen1995 drew barrymore shirt lift
