Solution

The correct option is B $237.3$
Mean refers to the average amount in a given group of data. In this measure of central tendency, all the data are added up and then divided by the number of figures in the data in order to ascertain the mean.

Mean $\frac{(201 + 202 + 207 + 222 + 276 + 201 + 246 + 212 + 285 + 312}{10}$
$= 236.4$
