1.
if we plot the scatter plot of Y on X in excel then we will get similar graph to that in option (C) hence
option (C) is correct
2.
let equation is
y=a+bx
from the data we have
now b can calculated by
so equation is
y=2.74+0.519x
3.
there is a point in the graph that is outside the trend and influenting the graph
hence
option (D) is correct
