a. To calculate the mean, we add up all the readings and divide by the total number of readings: (210+202+163+184+199+159+130+159+122+103+108+92)/12 = 152.6 milligrams/deciliter
b. To calculate the median, we need to find the middle value when the readings are arranged in order. First, we need to arrange the readings in order: 92, 103, 108, 122, 130, 159, 159, 163, 184, 199, 202, 210. The middle two readings are 159 and 163, so we take the average of these two numbers: (159+163)/2 = 161 milligrams/deciliter. Therefore, the answer is D.
