The correct answer is given as follows:
Step-by-step 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
