Question

What is the mean for the data set below?1454543525342123A 25.1B 29.5C 32.5D 40.0

Answer 1

Given a data set, we can find the mean by adding all the values and then dividing the sum by the number of values.

In this case, we have 8 values, then, the mean is:

`\begin{gathered} \mu=(14+54+54+35+25+34+21+23)/(8)=(260)/(8)=32.5 \\ \Rightarrow\mu=32.5 \end{gathered}`

therefore, the mean is 32.5
