The study at McDonalds found drive-thru customers waited an average of nine minutes with a standard deviation of 3 minutes. Assume the distribution of the wait time follows the normal probability distribution. if we select a customer at random, find the probability that the customer wait: 1) Between 4 and 6 minutes? 2) more than 6 minutes? 3) Less than 3 minutes? 4) What waiting time represents the middle 65%? 5) What waiting time represents the top 10%

Please do it in a google spreadsheet and share the link

Here is the answer but I need it typed into a google spreadsheet!!!!!!!!!

Step 5/8 4) The waiting time represents the middle 65% P(-z z) = 0.65 p(Z
