Statistics

Consider the following frequency distribution :


.tg {border-collapse:collapse;border-spacing:0;}
.tg td{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px;
overflow:hidden;padding:10px 5px;word-break:normal;}
.tg th{border-color:black;border-style:solid;border-width:1px;font-family:Arial, sans-serif;font-size:14px;
font-weight:normal;overflow:hidden;padding:10px 5px;word-break:normal;}
.tg .tg-baqh{text-align:center;vertical-align:top}
.tg .tg-0lax{text-align:left;vertical-align:top}

Class :	10-20	20-30	30-40	40-50	50-60
Frequency :	\(\alpha\)	110	54	30	\(\beta\)

If the sum of all frequencies is 584 and median is 45, then | \(\alpha\) \(-\) \(\beta\) | is equal to _______________.
