Question

1. Determine, and explicitly provide, the probability of observing a flexed bicep circumference (in inches) of 18.00 (N = 200, M = 14.80, SD = 1.42) in a sample of college-aged men

to do this problem what equation do I use and how do I input it correctly because the answer I got was 1% but that doesn't seem correct.
