Binomial Distributions

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.

Pivot table made above

As we can observe that in the outcome 1 the defective were 1 out of 40 while for outcome 2 the defectives have increased to 3.

Hence we can say that the quality of the new sample is not acceptable since 3/40 i.e. 7.5% defective samples are now produced.
