Discussion Post: 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 2524504910095200193
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.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
