A study comparing the resting heart rate of four different types of elite athletes recruited: 10 cyclists, 10 triathletes, 10 so
ccer players, and 10 baseball players. The resting heart rate of each athlete was measured, and the following hypothesis was tested using ANOVA: "Type of sport is a factor in elite athletes' resting heart rate." The BETWEEN groups sum of squares was calculated to be 1,170.5, and the WITHIN groups sum of squares was calculated to be 8,470.1. (NOTE: These are not the mean sum of squares) Calculate the F-statistic to two decimal places.
I would say the answer is J because follow the traingle sum theorem, all angles add to 180. There are 2x and you know that one is 80. Hope this helped! :)
