Question

The following is a list of 5 measurements.5, 17, 10, 13, 19Send data to calculatorSuppose that these 5 measurements are respectively labeled X2, X2, ..., Xs. Compute the following.5Σ (4)i=1

Answer 1

We will have the following:

$\sum ^5_{i=1}(x_i)^2=(5)^2+(17)^2+(10)^2+(13)^2+(19)^2\Rightarrow\sum ^5_{i=1}(x_i)=944$

So, the given sum is equal to 944.
