A professor of women's studies is interested in determining if stress affects the menstrual cycle. Seventeen women are randomly sampled for an experiment and randomly divided into two groups (n1= 9 and n2=8). The first of the groups is subjected to high stress for two months while the second lives in a relatively stress-free environment. The professor measures the menstrual cycle (in days) of each woman during the month. The high stress group had a mean menstrual cycle length of (M1) %3D
