The correct answer is given as follows:

Explanation:

Mean is the average in a common or informal way. It can be calculated by Adding the total numbers up and divide them by the total number of values in the set.

In this case: 37 is the mean value that can be calculated by:

adding all the values: 36.7+36.8+36.9+37+37.1+37.2+37.3 = 259

Number of sets = 7

then mean = 259/7

= 37

Thus, the mean can be calculated by total value divided by the number of sets
