WebbFor example, a part of the standard normal table is given below. To find the cumulative probability of a z-score equal to -1.21, cross-reference the row containing -1.2 of the … WebbFind the area for the negative z-value and double it to obtain the p-value. For our example, the area less than z = -2.5 equals the region greater than z = 2.5, thanks to the symmetry. …

Webb26 mars 2024 · Definition: standard normal random variable A standard normal random variable is a normally distributed random variable with mean μ = 0 and standard deviation σ = 1. It will always be denoted by the letter Z. The density function for a standard normal random variable is shown in Figure 5.2. 1. Webb4 nov. 2024 · In this instance, the normal distribution is 95.3 percent because 95.3 percent of the area below the bell curve is to the left of the z-score of 1.67. Negative z-Scores and Proportions The table may also be used to find the areas to the left of a negative z -score. To do this, drop the negative sign and look for the appropriate entry in the table. jersey city waterfront restaurant
