According to the CIRP Freshman Survey, UCLA's Annual Survey of the Nation's

According to the CIRP Freshman Survey, UCLA's annual survey of the nation's entering students at four-year colleges and universities, conducted in 2010, female students were far less likely to report high levels of emotional health than male students (45.9 percent versus 59.1 percent) , a 13.2 percentage-point difference. This difference was reported as statistically significant. The statistically significant difference between male and female students means that

A) the difference between the two rates (45.9 percent versus 59.1 percent) is likely to have resulted from two groups whose true rates of high levels of emotional health were identical.
B) the difference between the two rates (45.9 percent versus 59.1 percent) is unlikely to have resulted from two groups whose true rates of high levels of emotional health were identical.
C) the difference between the two rates (45.9 percent versus 59.1 percent) is likely to have resulted from the difference in sample sizes between male and female students.
D) the difference in the two rates (45.9 percent versus 59.1 percent) is likely to have resulted from other factors, such as age and major, on which the two groups differed.
