By default, the standard normal distribution is displayed with mean μ = 0 and standard deviation o = 1. Change the mean and standard deviation values to display the normal distribution with mean μ = 26.2 and standard deviation o = 4.1. Settings Distribution Selection Normal Distribution Mean St. Dev. Notice there are two horizontal axes on the graph: the x-axis displays values of the random variable with the specified mean and standard deviation while the z-axis displays corresponding z- scores in the standard normal distribution. The y-axis displays the relative likelihood for the values of this random variable, x, to take on a given value. We will use this distribution calculator to specify the probability that values of the random variable will fall within a range of values. Look along the horizontal axes and locate x = 26.2. The corresponding z-score when x = 26.2 is z = X = Look again and locate z = 1.0. The corresponding x-value when z = 1.0 is
