(a) if the mean number is more than 2, find the largest possible value of x.

(b) if the median number of goals is 2, find the largest possible value of x

**drwls**, Wednesday, August 10, 2011 at 5:52amTotal # of matches: 7+x+5+3+1+4 = 20 + x

Total # of goals: 1*x + 5*2 + 3*3 + 1*4 + 4*5 = 43 + x

If x = 0, the mean per game is 43/20 = 2.15

If x = 1, mean = 2.095

If x = 2, mean = 2.045

if x = 3, mean = 2.000

The answer to a is x=2

The answer to b is x=3
