Question

TABLE 4

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	Total
Number of Transactions:	82	100	74	92	102	450
Number of Reported Errors	11	12	6	9	10	48
Total	93	112	80	101	112	498

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

1. 20.090

2. 9.488

3. 7.779

4. 13.277
