Mason mistakenly calculated the conditional relative frequency for female students who prefer playing sports to be 21%. What statistic did Mason actually calculate, and what should he have done differently? He calculated the marginal relative frequency of female students for prefer playing sports. The conditional relative frequency for female students who prefer playing sports is 34%. He calculated the joint relative frequency of female students who prefer playing sports. The conditional relative frequency for female students who prefer playing sports is 50%. He calculated the marginal relative frequency of female students who prefer playing sports. The conditional relative frequency for female students who prefer playing sports is 50%. He calculated the joint relative frequency of female students who prefer playing sports. The conditional relative frequency for female students who prefer playing sports is 34%.
I believe it's the 3rd option.
I already took it and the second option was wrong
18/87 = 21% this is the "joint relative frequency" for females who prefer sports
so that eliminates first and third options
for calculating conditional relative frequency for females, you need to look at below row : Female students 18. 35 53
its actually the last option !
