the following readings were obtain in an experiment
P(volt) 1.5 \ 2.5 \ 3.3 \ 3.9 \ 4/3 \ 4/6
R(amp) 0.30 \0.52 \0.66 \ 0.80 \ 086 \ 0.92
was asked to plot a graph of P against R
a, Calculate the slope and determine the error in the slope
b, If P and R are related by the equation p=a2R,determine the value of a and the standard error
