Question

Listed below are the overhead widhe (in cm) of al measured from photographs and the weights (in kg) of the seals. Construct a scatterplot, find the value of the linear correlation coefficient and find the clical values of using a -0.01.is here sufficient evidence to conclude that there is a linear correlation between overhead widths of seals from photographs and the weight of the seals?
