Question

you are a research scientist. in a study, the cholesterol levels of a group of participants were recorded as follows: 218, 205, 201, 190, 198, and 206. what is the average cholesterol level of these participants?
a 196
b 200
c 203
d 212
e 1,218

Explanation:

Step1: Sum the cholesterol levels

The cholesterol levels are 218, 205, 201, 190, 198, and 206. First, we sum them up: $218 + 205 + 201 + 190 + 198 + 206$. Let's calculate step by step: $218+205 = 423$; $423+201 = 624$; $624+190 = 814$; $814+198 = 1012$; $1012+206 = 1218$.

Step2: Calculate the average

There are 6 data points. The average (mean) is the sum divided by the number of data points, so $\frac{1218}{6}$. Dividing 1218 by 6: $1218\div6 = 203$.

Answer:

C. 203
