To use a three-week moving average forecast, we need to find the average of the number of patients in the past three weeks.

Week 5: Actual number of patients is 415

Week 4: 384 
Week 3: 411 
Week 2: 380

The three-week moving average for week 5 is:

(384 + 411 + 380)/3 = 391.67

Therefore, the forecast for week 6 using a three-week moving average forecast is greater than 398 but less than or equal to 406. Hence, the answer is C.
