Use the following prompt and scores provided to answer questions 5a-5e.

In an extensive study involving thousands of British children, Arden andPlomin(2006) found significantly higher variance in the intelligence score for males than for females. The following is hypothetical data, similar to the results obtained in the study. Note that the scores are not regular IQ scores but have been standardized so that the entire sample has a mean ofx=10 and a standard deviation ofs= 2.
