Question 364527
The amount of ice cream in a cone has a distribution with a mean of 3.2 ounces per cone and a standard deviation of 0.4 ounces. If there are 50 children to be served ice cream at a birthday party, find the probability that more than 165 ounces of ice cream will be served.
----------------------
165/50 = 3.3
t(3.3) = (3.3-3.2)/0.4 = 0.25
----
P(x > 3.3) = P(t> 0.25) = 0.4018
