Question

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1430 referee calls, with the result that 426 of the calls were overturned. Women challenged

761 referee calls, and 210 of the calls were overturned. Use a 0.01 significance level to test the claim that men and women have equal success in challenging calls.

(1). Identify the test statistic. (2) P-Value

Answer #1

To Test :-

H0 :- P1 = P2

H1 :- P1 P2

Test Statistic :-

is the
pooled estimate of the proportion P

= ( x1 + x2)
/ ( n1 + n2)

= ( 426 +
210 ) / ( 1430 + 761 )

=
0.2903

Z = 1.0753

Test Criteria :-

Reject null hypothesis if

= 1.0753 < 2.5758, hence we fail to reject the null
hypothesis

Conclusion :- We Fail to Reject H0

Decision based on P value

P value = 2 * P ( Z < 1.0753 )

P value = 0.2822

Reject null hypothesis if P value <

Since P value = 0.2822 > 0.01, hence we fail to reject the null
hypothesis

Conclusion :- We Fail to Reject H0

There is sufficient evidence to support the claim that men and
women have equal success in challenging calls.
