QUESTION:

Repeat Exercise 10.4 but assume that 50 orders are selected and the critical region is defined to be \(x \leq 24\), where x is the number of orders in the sample that arrived late. Use the normal approximation.

ANSWER:

Step 1 of 5

Normal approximation, also known as the normal approximation to the binomial distribution, is a statistical method that allows us to estimate probabilities for certain events in a binomial distribution by using the normal distribution as an approximation. The normal distribution, also called the Gaussian distribution or bell curve, is a continuous probability distribution that is symmetric and bell-shaped.
