Question

This Question: 1 pt | 20 of 20 (0 complete) ? This Test: 20 pts possible In a study of pregnant women and their ability to correctly predict the sex of their baby, 57 of the pregnant women had 12 years of education or less, and 43.9% of these women correctly predicted the sex of their baby. Use a 0.05 significance level to test the claim that these women have an ability to predict the sex of their baby equivalent to random guesses. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and conclusion about the null hypothesis. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution. Do the results suggest that their percentage of correct predictions is different from results expected with random quesses? Identify the null and alternative hypotheses. Choose the correct answer below OA. Ho:p=0.439 O B. Ho p 0439 OD, Hoip 0.439, OF. Higp=0.5 H P0.439 ???#01439 | H1: p#0.5 H: p> 0.439 Hi: p>0.5 H0: p=0.5 Hi: p0.5 OE. The test statistic is z= (Round to two decimal places as needed.) The P-value is(Round to four decimal places as needed.) Identify the conclusion about the null hypothesis. Do the results suggest that their percentage of correct predictions is different from results expected with random guesses? Ho.There sufficient evidence to warrant rejection of the claim that these women have an abity to predict the sex of their baby equivalent to random guesses ? very different r results expected with random The results for these women with 12 years of education or less suggests guesses at her percentage of correct predictions
