An institute conducted a clinical trial of its methods for gender selection. The results showed that 187 of 338 babies born to parents using a specific gender-selection method were boys. Use the sign test and a 0.01 significance level to test the claim that the method has no effect on the likelihood of a boy. Let p denote the population proportion of baby boys. Ignore the possibility of the method decreasing the likelihood of a boy. What are the null and alternative hypotheses? OA. Ho:p>0.5 H₁: p=0.5 OC. Ho: p=0.5 H₁: p20.5 Find the test statistic. B. Ho: p=0.5 H₁: p > 0.5 O D. Ho: p=0.5 H₁: p=0.5

Question
Transcribed Image Text:An institute conducted a clinical trial of its methods
for gender selection. The results showed that 187 of
338 babies born to parents using a specific
gender-selection method were boys. Use the sign
test and a 0.01 significance level to test the claim
that the method has no effect on the likelihood of a
boy.
Let p denote the population proportion of baby boys.
Ignore the possibility of the method decreasing the
likelihood of a boy. What are the null and alternative
hypotheses?
OA. Ho:p>0.5
H₁: p=0.5
OC. Ho: p=0.5
H₁: p20.5
B. Ho: p=0.5
H₁: p > 0.5
D. Ho: p=0.5
H₁: p=0.5
Find the test statistic.
Test statistic = (Round to two decimal places as
needed.)
