separate the highest 30% from the rest of the distribution.

Question

 for a standard normal distribution, graph the the normal distribution curve and find the Z value that separates the distribution as follows

Answer 1

Hi Mya,

 

To do this, we need to use the normal distribution table (there should be one in your textbook).

If we use the table to find the z-score that separates the top 30% from the bottom 70%, we get approximately 0.524.

 

Hope that helps.
