Question

Let Z be a random variable with a Standard Normal distribution (). Calculate the following probability. Include all four decimal places in your answer.

 

 

Answer 1

P(Z<-0.64)

if using ti-84 calculator

normalcdf(-10000, -0.64, 0,1) = 0.2611

or excel

=norm.s.dist(-0,64, TRUE) = 0.2611

Let me know if you have any questions.
