Thank you for the opportunity to help you with your question!

population mean = 205.5
population standard deviation = 8.6 

179.7-205.6/8.6= -25.8/8.6 WHICH IS EQUAL TO -3.

231.3-205.5/8.6=25.8/3 WHICH IS EQUAL TO 3. 

the z-score of -3=.0013

the z-score of 3=.9987

.9987-.0013=.9974 

so the final answer is .9974

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