P(-.95<z<.95) Still don't understand how to get it.
Thank you for the opportunity to help you with your question!
Find the value in a look up table of the Probability
of a z-score of less than 0.3293.
z=-0.95 has an area under
the curve0.3293 Find the value in a look up table of the probability of a z-score of less than 0.3293.
z=0.95 has an area under
curve of 0.3293 To find the area between
the two z-scores, subtract the smaller z-score value from the larger one. For
any negative z-score, change the sign of the result to negative.
Multiply-1 by each term inside
the parentheses Area=0.3293+0.3293
Add 0.3293 to 0.3293 to get 0.6585. Area=0.6585
