Question

=MATHEMATICAL READINESSSummation of indexed dataThe following is a list of 14 measurements.38. -82. 19. 84. -37.93.-31, -73, -50.-65.-31. -85, -48Suppose that these 14 measurements are respectively laSum of Xi/ 50 with i going from 1 to 14Round your answer to at least two decimal places.

Answer 1

In order to calculate the sum we need to iterate over the "xi" variable going from 1 to 14 and adding all the data.

`\begin{gathered} \sum ^(\infty)_(n\mathop=1)(x_i)/(50)\text{ = }\frac{38\text{ - 82}+19+84-37.93-31-73-50-65-31-85-48}{50} \\ \sum ^(\infty)_{n\mathop{=}1}(x_i)/(50)\text{ = }(-361.93)/(50)\text{ = -7}.2386 \end{gathered}`

The answer is approximately -7.24.
