Questions About Probabilities and Normal Distributions

A famous restaurant owner noticed that in the past 20 years his hamburger supply shows a normal distribution in weight. Average weight was 10.0 ounces with a standard deviation of 0.3 ounces after they were cooked. (Consider normal distribution)

* What is a probability that a customer gets a hamburger that weighs at least 10.5 ounces?

* What is the probability that a customer gets a hamburger that weighs at least 9.6 ounces?

* If a customer gets a hamburger that falls in the lower 30% of the weight distribution, what is the maximum weight of his hamburger?

* What is the probability that we select 3 customers at random and all 3 were served hamburgers that were 9.5 ounces or less?

* What is the probability that a customer gets a burger that is 9.4 ounces to 10.3 ounces?
