Given your statistical knowledge, you have been asked to assist the quality control manager of a local manufacturer in establishing and seeing that the factory conforms to standards set by management. The facility manufactures a new electronic toy. The factory can produce 1000 toys per day. Management has indicated that initially they will be satisfied if the defect rate is 3% or less. Since you can’t quality-test every toy produced, you suggest that a random sample of 40 toys be taken. The results of testing 40 toys from today’s production line yields the results shown in the “WA3_Outcomes” Excel file Column 1.
Take a second sample of 40 toys.
The results of this sample are shown in “WA3_Outcomes” Excel file Column 2.
