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?
