A systems engineer is experimenting with a system that has traditionally produced an average quality index of 10 and a standard

deviation of 10. She is experimenting with a new method, and she will produce n outputs that are normally distributed with a new mean and the same standard deviation of 10. A standard Single Sample Z Test will be used. You would like to find a value of n such that the type I error rate is less than 5% and the type II error rate is less than 10% if the population mean of the new method is 8. Try the following values for n: 100, 200, 300, 400 and 500. Which ones meet the criteria? Which one would you choose considering that samples cost money?

Answer:

For company A, y = 24x + 42

For company B, y = 28x + 25

Step-by-step explanation:

x is the number of containers

y is the total cost

For company A, y = 24x + 42

For company B, y = 28x + 25

For the cost of both companies to be the same, then

24x + 42 = 28x + 25

28x - 24x = 42 - 25

4x = 17

x = 4.25

Mr Lycan would have to order about 4 containers so the cost would be the same from each company
