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 the  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.

Area=0.3293-(-0.3293)

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

Please let me know if you need any clarification. I'm always happy to answer your questions.
