Hello, I'm having trouble with this one question on my review sheet (yikes, and I have a chapter test on Statistics tomorrow!). The question is: What is the area under the standard normal curve that is within 1.5 standard deviations of z=1? a) 0.2838 b) 0.3050 c) 0.5637 d) 0.6853 e) 0.7714 The answer is D, but I don't know how to get that answer. Anyway, if anyone can help, that'll be GREAT!! Thanks so much!!
