Recall the definition of functionality (CTQ2) in POI case study. You have inspected 10 boxes of MSDs and couted the number of MSDs that are broken in each box as 10, 9, 5, 4, 5, 9, 6, 6, 9, 11. Based on these samples, you want to claim to your supplier for price negotiation that each box contains 7 or more broken pieces. Evaluate your claim at Significance level 5%.

1) Set up the hypothesis

2) Which test method do you need to use?

3) Evalute your hypothesis by showing p-value and your comments (You may use MINITAB for this)
