The manager of a warehouse would like to know how many errors are made when a product’s serial number is read by a bar-code read
er. Six samples are collected of the number of scanning errors: 36, 14, 21, 39, 11, and 2 errors, per 1,000 scans each. What is the mean and standard deviation for these six samples?
The mean of the answer is 20.5 because you add all of the number together and divide by 6 because there's 6 numbers. I'm sorry, but I don't know how to do the standard deviation... Hope this helped!
