For a normally distributed set of data, find the area under the normal curve between the mean and a piece of data with a z-score of -1.24

Question

What is the area under the normal curve between the mean and a piece of data with a z-score of -1.24?

Answer 1

P(z<0, the mean) = 0.50000 as I hope you already knew.

P(z<-1.24) = 0.10749, from table

 

The answer you seek is going to be the difference of the above two decimal values.

I hope you are gaining some understanding and self confidence by now with use of the Standard Normal Distribution Table!
