Suppose that 30% of female students and 25% of male students at a large high school are enrolled in an ap ® class. independent random samples of 20 females and 20 males are selected and asked if they are enrolled in an ap ® class. let ˆ p f represent the sample proportion of females enrolled in an ap ® class and ˆ p f represent the sample proportion of males enrolled in an ap ® class. is the 10% condition met?
20 is less than 10% of the large high school and 20 is less than males at the large high school.
the standard deviation of ˆ p f − ˆ p m is approximately .
the difference (female – male) in the that are enrolled in an ap ® class typically varies by from the true difference in proportions of
