Question

MLB Win The scatterplot compares the win percentage on June 1 (about 50 games) to the final win percentage on October 3 (162 games) of every Major League Baseball team for the 2010 season. 2010 MLB Season S 0450 400 0.350 S0 0.300 0.350 0.400 0.450 0.500 0550 0.600 0650 0.700 Win percentage on June 1 Of the 8 teams that made the playoffs in 2010, the least win total was 90. (in decimal form) b. Is it possible that a team with a win percentage less than 0.500 on June 1 made the playoffs? no

Answer 1

a) A team with 90 wins of the 162 played , the final win %would be

90 / 162 = 0.55556

Ans: 0.56

b) A win % of less than 0.5 means the team would have won less than

0.5 x 50 = 25 games out of 50 played.

To make the play offs they need to have a minimum of 90 wins in total

i.e they still have to win more than 90 - 25 = 65 games

and the no. of games left are 162 - 50 = 112

so after june 1 thy need to have a winning % of 65/112 = 0.58

which is very do-able

Ans: YES
