Answer:
0
Step-by-step explanation:
Here,
p=2
b=2
c=?
we know that,
c= p²-b²
=4-4
=0
Answer:
2.6
Step-by-step explanation:
The χ² = (observed - Expected)²/Expected
The expected wins :
n = 6
(45+33+44+39+42+37) / 6 = 40
χ² = (45-40)²/40 + (33-40)²/40 + (44-40)²/40 + (39-40)²/40 + (42-40)²/40 + (37-40)²/40
χ² = 0.625 + 1.225 + 0.4 + 0.025 + 0.1 + 0.225
χ² = 2.6
