You take the three zeros and put them back with the x s
(x-6)(x+5)(x-2) they are reversed when you put them back in
multiply the first two and get
simplify to
Multiply it out again and get
finally simplify and get
So the answer is the first one

Answer:
d) 6.750
<em>The chi - square value = 6.750</em>
Step-by-step explanation:
Given data
Starting Position 1 2 3 4 5 6
Number of Wins (O) 33 44 32 36 45 50
<u><em>Step(i) :</em></u>-
mean =
Expected frequency = 40
Number of Wins (O) : 33 44 32 36 45 50
Expected frequency(E) : 40 40 40 40 40 40
(O - E ) : -7 4 -8 -4 5 10
(O-E)² : 49 16 64 16 25 100
: 1.225 0.4 1.6 0.4 0.625 2.5
<u><em>Step(ii):-</em></u>
<u><em>The χ² test</em></u>
<em> χ² = ∑ </em><em></em>
<em> χ² = 1.225 + 0.4 + 1.6 + 0.4 +0.625 +2.5 = 6.75</em>
<em>The chi - square value = 6.750</em>
<u><em>Final answer</em></u><em>:-</em>
<em>The chi - square value = 6.750</em>
<u><em> </em></u>
