Area under the standard normal distribution curve between z = -2.05 and z = 2.05 is equals to 0.95962.
What is normal distribution curve?
" Normal distribution curve is a bell shaped curve , which is symmetrical from the mean and can meet the x- axis to its infinity."
Value used z score chart
when z = 2.05
area = 0.9798
when z = -2.05
area = 0.02018
Therefore,
Area under the standard normal distribution curve between given range =0.9798 - 0.02018
= 0.95962
Hence, area under the standard normal distribution curve between z = -2.05 and z = 2.05 is equals to 0.95962.
