Question

1) The Genetics and IVF Institute conducted a clinical trial of the YSORT method designed to increase the probability of conceiving a boy. As of this writing, 291 babies were born to parents using the YSORT method ,and 239 of them were boys .Use?=0.01significance level to test the claim that the YSORT method is effective in increasing the likelihood that a baby will be a boy. a. State the null and alternate hypotheses (write it mathematically) and write your claim. b. Find the standardized test statistic. c. Identify /separate the Rejection Region (Critical Region) from the Fail to Reject Region using the critical value. d. Find the p-value and interpret its meaning. e. Decide whether to reject or fail to reject the null using the p-value approach. f. Make an interpretation of your decision in the context of the claim. g. What is Type 1 error? Explain its consequence in the context of the problem. 1 h. Use the sample data to construct a 98% confidence interval estimate of the proportion of boys (?) . What does the confidence interval suggest about the claim that the YSORT method is effective in increasing the likelihood that a baby will be a boy (? > 0.5)?
