This renders a one sample t-test useless: we already know that test values in this range result in p > 0.05 and reversely. When testing for the lower or upper bound of the interval, p = 0.05 as SPSS quickly confirms. WebGeneralizing the 95% Confidence Interval Critical value, z /2 is a multiplier for a (1-α) × 100% For 95% CI, α = 0.5, so the Z-value of the standard normal is at 0.025, that is z = 1.96 For any probability value (1- ) there is a number z /2 such that any normal distribution has probability (1- ) within z /2 standard deviations of the mean. building balsa wood airplanes
