To determine the requested percentage, first identify the relevant counts from the pivot table. The row for CH (Chicago Hope) shows that High risk patients numbered 22, and the Grand Total for all patients is 403.

Next, compute the proportion of high-risk patients who came from CH by dividing the CH high-risk count by the overall total: 22 ÷ 403.

Calculating 22 ÷ 403 yields approximately 0.0546. Converting this to a percentage gives about 5.46%.

Rounding to one decimal place, the result is 5.5%.

So, approximately 5.5% of the patients were from CH hospital and at high risk. Note that this uses the grand total of patients (403) as the denominator, not just the CH hospital totals, to answer the specific question about the share of the entire patient cohort.
