Bank Model Consider a Bank consisting of an automatic teller machine (ATM) and teller lines. ATM provides people with a quick self-service for cash. More complex transactions, ex: paying bills, are completed by tellers, allowing customers more time without inconveniencing those customers looking for quick cash. Customer Arrival Rate: 0.8 per minutes Queue capacity for ATM: 15, for Tellers: 20 Number of Tellers: 4

00:01 In this problem of frequency distribution, we have to first find construct the relative frequencies to gram for the given data set using four eight classes.

00:15 So let's find the class width.

00:18 First, class width is equal to range divided by number of classes.

00:33 So here the range is 104 minus 61 divided by local.

00:44 Classes, eight.

00:46 So if we select the convenient value, the next convenient value, to come around five point simply so we can just move to six.

01:00 Now let's construct a frequency distribution table in order to construct the graph.

01:24 So here the class starts with 61.

01:38 You'll add 5 so that the classes does not overlap.

01:43 So 61 to 66, 66 to 67 to 66 plus 6, 72, 73 to 79, 79 to 84, 85 to 90, 91 to 91 to 96, 97 to 100 to 80, 100 to 80, 80, 488.

03:17 So let's find out frequency.

03:27 So 61 to 66.

03:35 1 .67 to 72.
