The data below gives the logarithm to the base 10 of the volume occupied by algal cells on succesive days, taken over a period for which the realtive growth rate is approximately constant:
X=Day Y=Log(Volume)
1 3.592
2 3.823
3 4.174
4 4.534
5 4.956
6 5.163
7 5.495
8 5.602
9 6.087
Calculate and interpret the sample correlation coefficient. By the method of least squares, fit log y=alpha+beta*x to the n=9 data points.
