96% Confidence Interval

My bad guys...on the homework tonight you can't just use the table to find our critical value (z star) for 96%. We'll have to use inverse norm (invnorm() on our calculator. Go to 2nd --> VARS to see the distribution menu and select invnorm. Then, think about the percent of data that lies to the left of our confidence interval (96%) (draw a Normal model if you're not sure). Enter this value (as a decimal) into invnorm and it'll give us the negative z-star (just make it positive!)
