Answer

The sum of terms = 5.7 + 6.6 + 7.2 + 9.3 + 6.2 = 35

Number of terms = 5

Arithmetic mean (A.M.) = Sum of termsNo. of terms=∑xin\dfrac{\text{Sum of terms}}{\text{No. of terms}} = \dfrac{∑x_i}{n}

∴A.M.=355=7.\therefore A.M. = \dfrac{35}{5} = 7.

Hence, the mean of 5.7, 6.6, 7.2, 9.3, 6.2 is 7.
