In a fisheries researcher's experiment, the correlation between the number of eggs in the nest and the number of viable (surviving) eggs for a sample of nests is r = 0.67.
The correlation r = 0.67 shows that the fact that the nests have different number of eggs explains
A) about 27% of the observed variation in the number of surviving eggs.
B) about 45% of the observed variation in the number of surviving eggs.
C) about 67% of the observed variation in the number of surviving eggs.
D) about 95% of the observed variation in the number of surviving eggs.
E) why some people fish at different places in the river.
