Use the following information for questions:
A researcher examined the folklore that women can predict the sex of their unborn child better than chance would suggest. She asked 104 pregnant women to predict the sex of their unborn child, and 57 guessed correctly. Using these data, the researcher created the following Minitab output.
-Based on the information in the output, what is the appropriate conclusion the researcher can make about p = proportion of pregnant women who can correctly predict the sex of their unborn child?
A) There is statistically significantly evidence against the null hypothesis that p = 0.5.
B) There is not statistically significant evidence against the null hypothesis that p = 0.5.
C) There is statistically significant evidence against the null hypothesis that p = 0.548.
D) There is not statistically significant evidence against the null hypothesis that p = 0.548.

Quizplus · Accepted Answer

Without the specific output data, the correct conclusion cannot be determined directly. However, choice B suggests that there is not statistically significant evidence against the null hypothesis that p = 0.5, which typically means that the data did not provide enough evidence to reject the null hypothesis that the proportion of pregnant women who can correctly predict the sex of their unborn child is 0.5 (or 50%). This is a common conclusion when statistical tests fail to show a significant difference from a specified proportion.
