How do I solve this in Excel: Let x be a normally distributed random variable with mean 16 and standard deviation 14. Please express your answer as a number between 0 and 100. If you want to write 52%, please enter 52. What is the probability that x is between 14 and 28?

Answer #1 
 Z = (X - MU)/SIGMA

mean = 16; stdev = 14

What is the probability that x is between 14 and 28?

Z-Score for 14 = (14-16)/14 = -0.14
Z-Score for 28 = (28-16)/14 = 0.86

= 0.3608

the probability that x is between 14 and 28 is 36 %
