In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is The parameter is the mean or expectation of the distribution (and also its median and mode), while the parameter is its standard deviation. The variance of the dist… Webb17 mars 2024 · To determine the probability that X is less than or equal to 5 we need to find the z -score for 5 in the normal distribution that we are using. Thus z = (5 – 10)/2.236 = -2.236. By consulting a table of z -scores we see that the probability that z is less than or equal to -2.236 is 1.267%.
