Question

A soft drink machine outputs of29 ounces per cup. The machines output is normally distributed with with a standard deviation of 4 ounces. What is the probability of filling a cup between 34 an 35 ounces? Draw a normal curve to represent this situation

Answer 1

You will use the z score to find this so need a z score chart.

Step-by-step explanation: Remember to take what you want (35 ounce) minus the mean( 29) then divide by the standard deviation(4). Then you look up this number on the z score chart to find your probability of less than 35 ounces. You could then do the same thing using 34 ounces since your final answer will be between these two numbers.
