If the coach wanted to know if the proportion of basketball players who are over 72 inches is more than 85%, what are the null and alternative hypothesis? Select the correct answer below: H0: p=0.85; Ha: p<0.85 H0: p>0.85; Ha: p=0.85 H0: p=0.85; Ha: p>0.85 H0: μ=0.85; Ha: μ>0.85

Answer 1

H0: p=0.85;

Ha: p>0.85

Explanation:

What was being tested is that:

the coach wanted to know if the proportion of basketball players who are over 72 inches is more than 85%.

The null hypothesis which we are testing against would be that the proportion of basketball players who are over 72 inches is 85%.

H0: p=0.85;

Ha: p>0.85
