Can you explain how to do this problem
The following is a list of 11 measurements:
72, 28, 56, -47, -36, -41, 21, -31, -56, 41, -54 .
Suppose that these 11 measurements are respectively labeled x1, x2,...x11 . (Thus,72 is labeled x1 ,28 is labeled x2 and so on.)
Find 11 looks like a E under that is i=1 than xi over 29
Round your answer to at least two decimal places.
To solve this problem, we need to find the expression given by:
11∑(i=1) xi/29
Let's break down the steps to solve it:
Step 1: Calculate the sum of all the measurements xi.
Add up all the given measurements:
72 + 28 + 56 - 47 - 36 - 41 + 21 - 31 - 56 + 41 - 54 = -27
Step 2: Divide the sum by 29.
-27/29 = -0.9310 (rounded to four decimal places)
Step 3: Multiply the result by 11.
-0.9310 * 11 = -10.241 (rounded to three decimal places)
Therefore, the value of the expression is -10.241 (rounded to three decimal places).
