The following is a list of 5 measurements:
[tex]\[ 5, 16, 6, 13, 8 \][/tex]

Suppose that these 5 measurements are respectively labeled [tex]\( x_1, x_2, \ldots, x_5 \)[/tex]. Compute the following:
[tex]\[ \sum_{i=1}^5\left(x_i\right)^2 \][/tex]
[tex]\(\square\)[/tex]



Answer :

To compute the sum of the squares of the given measurements [tex]\( x_1, x_2, \ldots, x_5 \)[/tex], follow these steps:

1. Identify the values of the measurements:
[tex]\[ x_1 = 5, \quad x_2 = 16, \quad x_3 = 6, \quad x_4 = 13, \quad x_5 = 8 \][/tex]

2. Square each individual measurement:
[tex]\[ x_1^2 = 5^2 = 25 \][/tex]
[tex]\[ x_2^2 = 16^2 = 256 \][/tex]
[tex]\[ x_3^2 = 6^2 = 36 \][/tex]
[tex]\[ x_4^2 = 13^2 = 169 \][/tex]
[tex]\[ x_5^2 = 8^2 = 64 \][/tex]

3. Sum the squares of the measurements:
[tex]\[ \sum_{i=1}^5 x_i^2 = x_1^2 + x_2^2 + x_3^2 + x_4^2 + x_5^2 \][/tex]
[tex]\[ = 25 + 256 + 36 + 169 + 64 \][/tex]
[tex]\[ = 550 \][/tex]

Therefore, the sum of the squares of the measurements is:
[tex]\[ \boxed{550} \][/tex]
