factory is making scented candles. Every day a sample of 6 candles is taken from the production process and their weight (in grams) is measured. Over the last 30 days, the measurements were taken and the data is in this Excel file(same as in the previous question).

Suppose that the specification limits established for this process are 40 grams (lower) and 120 grams (upper), with 80 grams being the target value. How many defective products did this process generate out of the 30 samples?
