Assigned Media An institute conducted a clinical trial of its methods for gender selection. The results showed that 157 of 283 babies bom 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 hypotheses? 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 A. Ho: P> 0.5 OB. Ho P = 0.5 Hip= 0.5 H1 : p>0.5 CC. Ho: P=0.5 O D. Ho: P = 0.5 H,: p > 0.5 H1 : p /0.5 Find the test statistic. 4 Test statistic = (Round to two decimal places as needed.)
