5. Approximately between 7 to 14 % of new mothers are affected by \"postnatal depression' which may result from the stress of a complicated delivery. To test the relationship between the type of delivery and the postnatal depression, a group of 10934 women were selected. Of the 10545 who delivered naturally, 1025 suffered postnatal depression. Of the 389 who delivered by voluntary C-section, 48 developed postnatal depression (a) [2 marks] Create a contingency table with the explanatory variable in the columns and the response variable in the rows. (b) [2 marks] Generate 95% condence interval for the risk of depression between women with natural delivery. (0) [2 marks] Generate a 95% condence interval for the difference risk of depression between women with natural delivery and voluntary C-section. (d) [2 marks] Construct a 95% Condence interval for Relative Risk of postnatal depression under the two procedures. (e) [2 marks] Construct a 95% Condence interval for Odd Ratio of postnatal depres- sion under the two procedures. (f) [1 mark] Interpret the condence interval for the Odd Ratio
