Question: Two telecommunication systems are to be compared. A random sample of 14 users of one system independently rate the system on a scale of 0 to 100. An independent random sample of 12 users of the other system rate their system on the same scale. The data are as follows.
System A: 65, 67, 83, 39, 45, 20, 95, 64, 99, 98, 76, 78, 82, 90
System B: 45, 57, 76, 54, 60, 72, 34, 50, 63, 39, 44, 70
Based on these data, are the two telecommunication systems equally liked? Explain.
