The weight of one batch must be 4.6 lbs. to make constant size of biscuits. The bakery has a low specification limit of 4.5 lbs. and upper specification limit of 4.7 lbs. The standard deviation is 0.1 lbs.

1.How many defects would there be in one million batches (you can use Excel spreadsheet or Table 9.1 in Textbook)?

2.Owner wants to reduce its defect probability 0.0051(5,100 PPM). To what level would they have to reduce the standard deviation in the process to meet this target? (you can use Excel spreadsheet or Table 9.1 in Textbook)
