Question

An article describes a study done by a certain psychologist in which he found that women who are trial lawyers (litigators) are more likely to have male children than are women lawyers who are not trial lawyers. According to the article, "57% of litigators' kids were boys vs. 40% boys for the others. The odds of this happening by chance are less than 4%, he says." (a) Choose the formula for the test statistic. The test statistic is z = Null Value/Null standard error The test statistic is z = Sample estimate/Null standard error The test statistic is z = Null standard error/Sample estimate + Null standard error The test statistic is z = Sample estimate - Null Value/Null standard error The test statistic s = Null standard error/Sample estimate - Null Value The numerator is (b) Consider the second sentence in the quote. What statistical term describes this result? Statistical significance Because the second sentence Indicates that the p-value was less than .04. (c) The quote from the article tells us that a p-value is less than 4%. Write one sentence that describes exactly what the p-value measures In this setting. The p-value is the probability that the difference in sample percents (tor samples of the size used) would be % or larger it there is no difference in the corresponding population percents. (d) The psychologist believes the result can be attributed to the women's testosterone levels because, in a previous study, he found that, an average, women litigators have higher testosterone levels than women lawyers who aren't litigators. Do you think this conclusion Is Justified? His conclusion is justified. His conclusion is not justified.

Explanation / Answer

Sol:

test statistic

=sample estimate-null value/null standard error

the numerator is

0.4-0.5=-0.1

Solutionb:

statistical significance

p value is greater >0.04

solutionc:

4%
