First, let's calculate the total reimbursement for all cases, which is the reimbursement per case multiplied by the total number of discharges: $4,914 * 210 = $1,031,940. Next, let's calculate the total amount of reimbursement affected by errors. Since we know that 27 cases increased reimbursement and 20 cases decreased it, we can multiply these numbers by the reimbursement per case: Increased reimbursement: $4,914 * 27 = $132,678 Decreased reimbursement: $4,914 * 20 = $98,280 Now, let's calculate the percentage of the total reimbursement that these represent: Percentage of increased reimbursement: ($132,678 / $1,031,940) * 100 = 12.86% Percentage of decreased reimbursement: ($98,280 / $1,031,940) * 100 = 9.52% So, the cases with errors increased the total reimbursement by $132,678 or 12.86%, and decreased the total reimbursement by $98,280 or 9.52%. please explain the result and the effect in the hospital
