Send data to calculator
Suppose that these 13 measurements are respectively labeled x1, x2, ..., x13. (Thus, 16 is labeled x1, −31 is labeled x2, and so on.) Compute the following.
Σ=i1134xi

wth is with the little mtn top and what are you talking about like fix your words and accually make sence with them and i like was in a completly different question like three times like it seems like your ilitteret
