A verticle line is drawn through a normal distribution at z=.80. What proportion of the distribution is on the right-hand side of the line?

Step 1

**The standard normal distribution:**

A continuous random variable *Z* is said to follow standard normal distribution if the probability density function of *Z* is,

Step 2

**Computing the proportion of the distribution is on the right side of the line at z = 0.80:**

A vertical line is drawn at z=0.80. The proportion of the distribution is on the right side of ...
