A researcher found a study relating the mortaly rates for women aped 65 to 74 , y. to the proportion of calories fiom swoeteners in their diet \( x \). When researchers botoed at the association of \( \mathrm{x} \) and \( \mathrm{x} \) they found that the coefficient of determination was \( r^{2}=0,486 \)
Select a conclusion that the researcher can make from this dath.
a.) The comrebtion coefficient, t, is 0697 .
b.) The cometation coetticient, is is 0.236 .
c) About \( 70 \% \) of the variation in propertion of calories in smotbeners is explained by a linear relationahip with mortality reses.
d) About St2 of the variation in mortalty rales is explained by a inear rebtationthip with proportion of
