The following is a list of 11 measurements: -2,82,87,-1,-51,-2,53,87,-20,32,35

Suppose that these 11 measurements are respectively labeled. x1,x2・・・・・x11.(Thus,-2 is labeled x1,82 is labeled x2 and so on.)
find ・_(i=1)^11・x1/49

Round your answer to at least two decimal places.

Answer #1
Maybe if you would repost (again) and this time proofread for nonsense symbols that only you know what they mean.

What is
"x1,x2・・・・・x11.(Thus,-2 is labeled x1,82 is labeled x2 and so on.)
find ・_(i=1)^11・x1/49"

Your question is not clear.

What are you supposed to do with this list of numbers?

Answer #2
I get
add -2,82,87,-1,-51,-2,53,87,-20,32,35=300

300/49=6.12244

Round two decimals = .061244 or 61.22? I don't know which way I should go.
