The answer to your question is -19
Α = 1- (95/100) = 1-0.95 = 0.05
p = 1- α/2 = 1- 0.05/2 = 1-0.025 = 0.975
Degrees of freedom, df = Sample size -1 = 11-1 = 10
From t-tables, with cumulative probability pf 0.975 and df of 10,
Critical value = 2.228
$57.60 is the correct answer
Total games= 20+8+14
=42 games
Fraction of tied games= 8/42
reduce the fraction so that it's 4/21
The ratio would be 4:21
