Question

Since an instant replay system for tennis was introduced at a major​ tournament, men challenged 14051405 referee​ calls, with the result that 424424 of the calls were overturned. women challenged 746746 referee​ calls, and 229229 of the calls were overturned. use a 0.010.01 significance level to test the claim that men and women have equal success in challenging calls. complete parts​ (a) through​ (c) below.
a. test the claim using a hypothesis test. consider the first sample to be the sample of male tennis players who challenged referee calls and the second sample to be the sample of female tennis players who challenged referee calls. what are the null and alternative hypotheses for the hypothesis​ test

Answer 1

Answer:

We accept the null hypothesis that men and women have equal success in challenging calls.

Explanation:.

Given

N = Number of challenges by men = 1405

Y = Challenges overturned = 424

M = Number of challenges by women = 746

X = Challenges overturned = 229

First we calculate the probability of successful challenge overturn

For men;

Let P1 = Probability of challenge overturn

P1 = 424/1405 = 0.3018

For women;

Let P2 = Probability of challenge overturn

P2 = 229/746 = 0.3070
