(please don't use software programme. Thanks)

Compute a rank correlation between change in
weight and change in HgbA1c, each over 1 year. Use this measure to directly test the hypothesis that change in
weight over 1 year is related to change in HgbA1c. Report
a two-tailed p-value, and provide a 95% confidence interval
for the underlying rank correlation
