The data below were gathered on a random sample of 5 basking sharks, swimming through the water and filter-feeding, i.e. letting the water bring food into their mouths.

Body Length (m) Mean Speed
4 0.89
4.5 0.83
4 0.76
6.5 0.94
5.5 0.94

a) What is the value of the correlation coefficient for these data?
b) Find the equation of the least squares line describing the relationship between x = body length and y = mean speed.
