Question

The percent of TOTAL cases that have a Z score less than or equal to 1.46 is ___. 

Answer 1

You want to convert the Z score over into a probability using either a Z table or some type of technology like Excel. When I do that I find that the a Z score of Z = 1.46 corresponds to a cumulative probability of 0.9279.

That means that 92.79% of all data points in a normal distribution have a value less than or equal to the data point with a Z score of 1.46.
