Sampling Distribution

A computer scanner can read a bar code on a package correctly 97% of the time. One company monitors the accuracy of the scanner by randomly sampling packages and verifying that each package has been correctly scanned. Random samples of size n = 25, 50, 100, and 200 have recently been taken with the following results.

Sample Size, n Number Correctly Scanned

25 24

50 49

100 95

200 193

To complete this activity, use Excel to:
- Calculate the sample proportion for each sample size.
- Calculate the single-proportion sampling error for each sample size.
- Calculate the probability of finding 198 correctly scanned packages, for a sample of size n=200.
