Probabilities of normal distribution
WebbThe probability density function of the normal distribution results in a graph like the one shown below. The normal distribution is non-zero over the entire real line, but values beyond ±4 sigma would appear to be zero on even high-resolution graphs which is why they are rarely plotted. WebbX is a normally distributed random variable with mean ( μ) 84 and variance ( σ 2) 12, calculate: P ( X − 84 > 2.9) If X is normally distributed with mean ( μ) 400 and standard deviation ( σ) 8, find the value of k such that: P ( X − 400 < k) = 0.975 X is normally distributed random variable with mean m and standard deviation s .
