x = number of hours
want to find probability (P) x >= 13
x is N(14,1) transform to N(0,1) using z = (x - mean) / standard deviation so can look up probability using standard normal probability table.
P(x >= 13) = P( z > (13 - 14)/1) = P(z > -1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413
To convert that to percentage, multiply 100, to get 84.13%
Hello,
*I will move straight to the math. If you have questions, ask away! :)
* All calculations are in “degree mode” for a TI calculator or other calculator.
I will apply Laws of Sines/Cosines and inverse functions for your math.
