- What is the probability of a z-score greater than -1.97?

Step 1

**The normal distribution:**

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

Step 2

**The z-score:**

The *z*-score corresponding to the value *x* of a normally distributed variable, *X* with mean and standard deviation can be obtained as:

Step 3

**An important property of the normal distribution:**

The normal distribution is symmetric. Thus, for any pai...
