In a study of pregnant women and their ability to correctly predict the sex of their baby, 56 of the pregnant women had 12 years of education or less, and 44.6% of them correctly predicted the sex of their baby. Use a 0.05 significance level to test the claim that these women have no ability to predict the sex of their baby, and the results are not significantly different from those that would be expected with random guesses. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal distribution as an approximation of the binomial distribution. The test statistic is z=|. (Round to two decimal places as needed.) |. (Round to four decimal places as needed.) The P-value is Identify the conclusion about the null hypothesis and the final conclusion that addresses the original claim. V sufficient evidence to warrant rejection of the claim that these women have no ability to Ho. There predict the sex of their baby. The results for these women with 12 years of education or less suggests that their percentage of correct predictions very different from results expected with random guesses.

Question
Transcribed Image Text:In a study of pregnant women and their ability to correctly predict the sex of their baby, 56 of the pregnant women had 12 years
of education or less, and 44.6% of them correctly predicted the sex of their baby. Use a 0.05 significance level to test the claim
that these women have no ability to predict the sex of their baby, and the results are not significantly different from those that
would be expected with random guesses. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion
about the null hypothesis, and final conclusion that addresses the original claim. Use the P-value method. Use the normal
distribution as an approximation of the binomial distribution.
The test statistic is z=|. (Round to two decimal places as needed.)
|. (Round to four decimal places as needed.)
The P-value is
Identify the conclusion about the null hypothesis and the final conclusion that addresses the original claim.
V sufficient evidence to warrant rejection of the claim that these women have no ability to
Ho. There
predict the sex of their baby. The results for these women with 12 years of education or less suggests that their percentage of
correct predictions
very different from results expected with random guesses.
