Determine the proportion of mild cases of atherosclerosis that were effectively dealt with using treatment A. Determine the proportion of mild cases of atherosclerosis that were effectively dealt with using treatment B.

Answer 1

We are asked to find the proportion of mild cases that were effectively dealt with using treatment A. First we will find the total number of cases that were dealt with using treatment A, that is:

`N_{\text{cases}}=\text{effective + not effective}`
`N_{\text{case}}=310+80=390`
