The probability of z occurring in the indicated region is 0.9772 or 97.72%.
What is z-value?
A z-value, in statistics, represents the number of standard deviations a data point is from the mean in a normal distribution.
To find the probability of z > -2
P(Z > -2)
Let's use the standard normal distribution table to find P(Z > -2) and the subtract the value from 1.
From standard normal distribution table
P( z = -2) = 0.0228
Therefore,
P(Z > -2) = 1 - P(z = -2)
= 1 - 0.0228
= 0.9772
Or
0.9772 * 100 = 97.72%
Therefore, the probability of z occurring in the indicated region is 0.9772 or 97.72%.
