"Could you explain why you added (2.326*0.020) to 2.50? I tried the following, and got a different answer. Thank you.
Probability(X > 2.500) = 0.99
2.326 = (2.50 - u)/0.020
u = 2.4534gm " "Thank you" "It's good, but what are the specific plasma waves called that are found in the F1 regions between 100kHz and 2.8MHz" "Amazing help as always." "Awesome! Thanks for the help!"
