A computer used by a 24-hour banking service is supposed to randomly assign each transaction to one of 5 memory locations. A check at the end of a day's transactions gave the counts shown in the table to each of the 5 memory locations, along with the number of reported errors.

Memory Location: 1 2 3 4 5

Number of Transactions: 82 100 74 92 102

Number of Reported Errors 11 12 6 9 10

The bank manager wanted to test whether the proportion of errors in transactions assigned to each of the 5 memory locations differ.

Which test would be used to properly analyze the data in this experiment?

1. 2test for difference among more than two proportions
2. 2test of independence
3. McNemar test for the difference among more than two proportions
4. McNemar test for the difference between two proportions
