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) of 33.4 and variance (51) of 4.6. The low stress group had a mean (M2) of 26.2 and variance (52) of 3.475. Test the %3D
