To compute the probability value using normal distribution for the given data.
Central Limit Theorem Area under a Curve:
The manufacturer of a coffee dispensing machine claims the ounces per cup is normally distributed with population mean equal to 8 ounces and standard deviation equal to 0.9 ounces. If 50 cups of coffee were measured, what is the probability that:
The sample mean per cup is more than 8.4 ounces?
