Have you been taught to use tables to find out how many standard deviations the 75th percentile is above the mean?
Here's the question, I just need help on how to solve it because I have tried and im always wrong :/...
Use technology to find the per capita consumption that corresponds to a cumulative area of 0.75 in a normal distribution with a mean of 18.7 and a standard deviation of 4.1
the 75th percentile of annual consumption is ______.
please and thank you!!!
