To find the upper control limit (UCL) for a c chart, we use the formula:

UCL = c + 3*sqrt(c)

Where c is the average number of medication errors per month.

c = 37/12 = 3.08 (rounded to two decimal places)

Substituting c into the formula, we get:

UCL = 3.08 + 3*sqrt(3.08)
UCL = 3.08 + 8.35
UCL = 11.43

Therefore, the Upper Control Limit (UCL) for Jake's c chart is 11.43, which is closest to answer choice C.
