Question

explain while the total area of the region between z = negative 2 and z = positive 2 is 0.95 44 or 95 point 44%?​

Answer 1

Given :   total area of the region between z = -2 and z = 2 is 0.9544 or 95.44%​

To Find : Explain  

Solution:

z score = ( Value - Mean ) / SD

Hence z = - 2 Means

That  2 SD left of Mean

Z = 2 means  2 SD right of Mean

Refer z score table

z = - 2 refers to 0.228

=> 2.28 % data if below  z = - 2

z = - 2 refers to 0.9772

=>97.72  % data if below  z =  2

Hence Data between z = - 2  and z = 2

is  97.72  % - 2.28 %

= 95.44 %

= 0.9544
