calculate the average (mean) of the data shown, to two decimal places\nx\n19.9\n2.3\n15\n28\n8.8\n20.5\n20.1\n7.3\n26.6
Answer
Explanation:
Step1: Sum the data values
$19.9 + 2.3+15 + 28+8.8+20.5+20.1+7.3+26.6=148.5$
Step2: Divide by number of data points
There are 9 data - points. So, the mean is $\frac{148.5}{9}=16.50$
Answer:
$16.50$
