Question

The same student (as in the previous question) realizes that he has forgotten to zero the balance before measurements of data set #1. After correcting the zero of the balance, he repeats measurements. The second set of data with the properly zeroed balance is as follows: 547 g, 554 g, 546 g, 554 g, 548 g, 545 g, 546 g, 555 g, 553 g, 552 g Part A Calculate the average value of the second set of measurements obtained with the properly zeroed balance.

Answer 1

The average value of the second set of measurements obtained with the properly zeroed balance is 550g.

Explanation:

The average value of a set is the sum of all the elements of the set divided by the cardinality(number of elements) of the set.

Here, our set of data with the properly zeroed balance is as follows:

547 g, 554 g, 546 g, 554 g, 548 g, 545 g, 546 g, 555 g, 553 g, 552

There are 10 values in this set, to the average value is:

`A = (547 g + 554 g + 546 + 554 g + 548 g + 545 g + 546 g + 555 g + 553 g + 552g )/(10)`

`A = (5500)/(10)`

`A = 550g`

The average value of the second set of measurements obtained with the properly zeroed balance is 550g.
