Question:
Predicting Gender of Baby In the same study cited in the preceding exercise, 45 of the pregnant women had more than 12 years of education, and 32 of them made correct predictions.
Use these results to test the claim that women with more than 12 years of education have a proportion of correct predictions that is greater than the 0.5 proportion expected with random guesses. Use a 0.01 significance level. Do these women appear to have an ability to correctly predict the gender of their babies?
Testing Claims About Proportions. In Exercises 9–28, test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, or critical value(s), then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Use the P-value method unless your instructor specifies otherwise. Use the normal distribution as an approximation to the binomial distribution, as described in Part 1 of this section.
