Normal Distribution

[Laura517]

Hi David,

Could you please help in solving the below question from GARP.

Assume that a random variable follows a normal distribution with mean of 80 and standard deviation of 24. What percentage of this distribution is not between 32 and 116 ? Ans: 8.96%

Thanks in advance!

Thank you so much David! I was wondering whether the values 0.0228 and 0.0668 came from. I am clear on this now. Thanks again!
