A study has been conducted to investigate the association between type II diabetes and incidence of chronic kidney disease (CKD). 100 people with type II diabetes and 100 people with no diabetes were recruited into the study and followed up for 10 years. The participants had normal kidney function at recruitment and the primary outcome was whether the patients develop chronic kidney disease during follow-up. The dataset is saved in the file CKD.csv and can be downloaded from CANVAS (under Project 2 folder). The dataset contains 200 rows (one row per patient) and three columns - Subject: subject number (not to be used in analysis) - Diabetes coded with 1 if the patient had type 2 diabetes at recruitment and 0 if the patient had no diabetes at recruitment. - CKD coded with 1 if the participant has developed CKD during follow-up and zero otherwise. (i) (ii) (iii) At the 5% level of significance test for an association between Diabetes and CKD incidence. Calculate a 95% confidence interval for the difference in proportions of patients with CKD in the diabetic vs non-diabetic group. Compare the results under points (i) and (ii) and formulate the conclusion
