The manager of a canning factory has noticed some cans with labels that are not glued on correctly. She wants to know how many cans might be affected. The manager asks each foreperson to check 20 random cans.
Here are the data from one sample:
Correctly glued label 17
Incorrectly glued label 3
Based on the results of this sample, estimate how many cans of the 10,000 produced by the factory have incorrectly glued labels.
cans
Based on the sample data, we can estimate that 3 out of 20 cans have incorrectly glued labels. This means that approximately 15% of cans in this sample have incorrectly glued labels.
If we assume that this percentage holds true for the entire production of 10,000 cans, then we can estimate that approximately 15% of 10,000 cans (or 1,500 cans) have incorrectly glued labels.
