To solve the problem of finding the sums [tex]\(\sum x_i\)[/tex] and [tex]\(\sum x_i^2\)[/tex], you'll need to add the entries in each column separately. Here’s how you do it step by step:
1. Sum of [tex]\(x_i\)[/tex]:
- Look at the first column of numbers:
[tex]\[
71.1, 68.9, 79.8, 66.9, 84.3, 77.7, 56.5
\][/tex]
- Add them together:
[tex]\[
71.1 + 68.9 + 79.8 + 66.9 + 84.3 + 77.7 + 56.5 = 505.2
\][/tex]
2. Sum of [tex]\(x_i^2\)[/tex]:
- Look at the numbers in the fourth column (the squared values):
[tex]\[
5055.21, 4747.21, 6368.04, 4475.61, 7106.49, 6037.29, 3192.25
\][/tex]
- Add these values together:
[tex]\[
5055.21 + 4747.21 + 6368.04 + 4475.61 + 7106.49 + 6037.29 + 3192.25 = 36982.1
\][/tex]
These calculations give you the results:
- The sum of [tex]\(x_i\)[/tex] is [tex]\(505.2\)[/tex].
- The sum of [tex]\(x_i^2\)[/tex] is [tex]\(36982.1\)[/tex].
These are the totals for each column based on the provided data.
