The Professor's Response

Hi Professor,
I am having trouble on how you found the answer for 13B in homework 6.2
I got the answer O, but how did you get 0.0001
Thank you

Hi Myriam,

I solved that problem using a graphing calculator. Zero is the correct answer if you are using the paper table. On an exam, you would not be required to find answers to questions that involved values off of the z table.
