Answer #1

Ans. The study of evolutionary history of the human races is based on the analysis of mitochondria DNA. The mitochondrial DNA has relatively higher rate of mutations than nuclear DNA, so the change in mtDNA sequences is more prominent and can easily be used to trace the point of changes (evolutions) during evolution of races.

The mitochondria is maternally inherited, i.e. inherited from mother, but not from father.

Therefore, sequencing the mtDNA of women (but not men) of all races and continents would reflect the evolutionary history of human races.

A recent study was done comparing the IQ scores of women and men. In a sample of 19 women, the average IQ score was 101.6 with a sample standard deviation of 7.8, and for a sample of 12 men, the average IQ score was 102.2 with a sample standard deviation of 9.5. Use a 0.01 level of significance to test the claim that the average IQ score for women and men is the same. Show your work to receive credit.

Arbitron Media Research Inc. conducted a study of the iPod listening habits of men and women. One facet of the study involved the mean listening time. It was discovered that the mean listening time for a sample of 11 men was 41 minutes per day. The standard deviation was 17 minutes per day. The mean listening time for a sample of 10 women was also 41 minutes, but the standard deviation of the sample was 9 minutes. Use a two-tailed...
