Activity 1 - Practice Exercises Draw standard normal curve described below and find the area of the region under the standard normal curve given the following: 1. to the left of z = 1.78 2. to the right of z = 2.12 3. between z = -1.23 and z = 1.94 Copy and fill in the blanks using the words in the box to demonstrate understanding of the key concepts of the Standard Normal Distribution and the areas under the standard normal curve. -3 -2 -1 0 1 2 3 symmetric z-table one (1) zero (0) z-scores between right equal left The standard normal distribution is a distribution of standardized values of a normal random variable called the It is the distribution that occurs when a normal random variable has a mean of and a standard deviation of The total area of the entire region under the standard normal curve is The standard normal curve is Thus, the area of the region to the left of z value is to the area of the region to the
