In an innings of a T20 cricket match (a team can bowl for 20 overs) 6 bowlers bowled from the elding side,
with a bowler allowed maximum of 4 overs. Only the three specialist bowlers bowled their full quota of 4 overs
each, and the remaining 8 overs were shared among three non-specialist bowlers. The economy rates of four
bowlers were 6, 6, 7 and 9 respectively. (Economy rate is the total number of runs conceded by a bowler divided
by the number of overs bowled by that bowler). This however, does not include the data of the best bowler
(lowest economy rate) and the worst bowler (highest economy rate). The number of overs bowled and the
economy rate of any bowler are in integers.
