An institute conducted a clinical trial of its methods for gender selection. The results showed that 371 of 658 babies born to parents using a specific gender-selection method were boys. Use the sign test and a 0.05 significance level to test the claim that the method increased the likelihood of having a boy. Find the null and alternative hypothesis. H0: p>0.5 p≠0.5 p=0.5 p<0.5 H1:H1: p<0.5 p=0.5 p>0.5 p≠0.5 If we consider + to represent a boy, then how many of each sign is there? Positive Signs: Negative Signs: Total Signs: What is the p-value? (Round to three decimal places.) What is the conclusion about the null? What is the conclusion about the claim?

Question
An institute conducted a clinical trial of its methods for gender selection. The results showed that 371 of 658 babies born to parents using a specific gender-selection method were boys. Use the sign test and a 0.05 significance level to test the claim that the method increased the likelihood of having a boy.
Find the null and alternative hypothesis.
H0:
- p>0.5
- p≠0.5
- p=0.5
- p<0.5
H1:H1:
- p<0.5
- p=0.5
- p>0.5
- p≠0.5
If we consider + to represent a boy, then how many of each sign is there?
Positive Signs:
Negative Signs:
Total Signs:
What is the p-value? (Round to three decimal places.)
What is the conclusion about the null?
What is the conclusion about the claim?
