a) (i) Complete the table above by inserting the missing figures.

  (ii) State the null hypothesis(Ho) tested on the table above.


b) (i) Calculate the correlation between slope angle and soil depth using the Spearman’s Rank Correlation Coefficient (rs) formula stated as: \inline \dpi{120} \LARGE rs = 1-\frac{6\sum d^{2}}{n^{3}-n}

where rs, the Spearman’s correlation coefficient, d2 is the sqyare difference in rank, and n is the number of sites.
