An institute conducted a clinical trial of its methods for gender selection. The results showed that 173 of 315 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 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. H₂: p=0.5 H₁: p20.5 OC. Ho:p> 0.5 H₁: p=0.5 Find the test statistic. Test statistic (Round to two decimal places as needed.) Find the P-value. P-value = (Round to four decimal places as needed.) Determine the proper conclusion. Choose the correct answers below. Since the P-value is than the significance level, the null hypothesis. There is OB. Ho: p=0.5 H₁: p *0.5 OD. Ho: p=0.5 H₁: p>0.5 evidence that the method used is effective in increasing the likelihood of a boy.
