According to the figure, which one is false about a normally-distributed random variable with mean M and standard deviation S? The probability of an observation at least one standard deviation more than M is almost 15.9%. The probability of an outcome at least three standard deviations away from M is less than 1%. Almost 95% of all observations are in the interval [M- 2.58 S , M + 2.58 S]. Almost 2.3\% of observations are less than M2S
