The Professor's Response

Hi Professor,

I have a question about something you said when using the z-table in reverse in section 5.3 you said look up the closest one on the table and if you get stuck in the middle like both are just as equal you add a 5? What do exactly do you add the 5 to? Can you further explain that trick?

  See the professor's answer below.

Hi Natalie,

I created a short video explaining what I meant.

Hope it helps,
