! find the mean of this data set. if neccary, round to the nerest tenth. 15.8,14.9,16.7,17.6,14.4
A 15.7
B 16.2
C 16.7
D 19.6
To find the mean of a data set, you need to sum up all the values in the data set and then divide it by the total number of values.
Let's calculate the mean using the given data set: 15.8, 14.9, 16.7, 17.6, 14.4
Step 1: Sum up all the values
15.8 + 14.9 + 16.7 + 17.6 + 14.4 = 79.4
Step 2: Divide the sum by the total number of values
79.4 / 5 = 15.88
Step 3: Round the mean to the nearest tenth
The mean is 15.9
Therefore, the correct answer is A) 15.9.
