I have for A:

R=nΣxy – (Σx)( Σy)/sqrt n(Σx^2)-(Σx)^2*sqrt n(Σy^2) – (Σy)^2

R = 6(676) – (47)(72)/sqrt6 (467) – (47)^2) * sqrt6 (1040_ – (72)^2

R = 4056 – 3384/sqrt2802 – 2209 * sqrt6240 – 5184

R = 672/sqrt593 * sqrt1056

R= 672/24.352 * 32.496

R = 672/791.346

R = 0.849, yes the P value is 0.032 which is smaller than 0.05 indicating that R is significantly different than zero.
