Answer 1

Answer: The mean change in the forecasted high temperatures is of 4.33 degrees.

------------------

* The mean of a data-set is given by the sum of it's observations, divided by the number of observations.

* There are 7 days, thus, there will be 6 changes.

------------------

* From Tuesday to Wednesday, the change is of |87 - 87| = 0.

* Following this logic, the changes are of 6, 5, 3, 6, 6.

* Thus, the average change will be of:

The average change in the forecasted high temperatures is of 4.33 degrees.
