In a tennis match, unforced errors are those types of mistakes that are supposedly not forced by good shots of an opponent. Reducing unforced errors is a key factor to win a tennis match. The following table shows the number of unforced errors of both players (winner and loser reported in pairs) in 10 tennis matches. Match: 1 3 4 6. 7 8. 9. 10 Winner: 68 19 28 28 53 28 50 30 44 22 Loser: 52 39 32 22 75 51 51 37 37 34 N (ux,o) be the average number of unforced errors of the winner in a tennis match, - N(µy,o) be the average number of unforced errors of the loser in a tennis match.
