B. Write a mathematical expression using the information from your table to answer the following questions:

1. What is the mean change in the forecasted high temperatures over the next 7 days? Remember, this can be found by averaging the values in the Difference column for the high temperatures. Show your work and steps. If your answer is not an integer, explain what two integers your answer is between.

ill give you brainliest please answer this is my 3rd time posting it and no one has answered

p.s nonsense answers WILL be reported :)

The mean change in forecasted temperature is the average value of the sum of difference in the forecasted temperature values which is -1.285 and lies in between the integers -2 and -1.

The mean change in the forecasted temperature can be calculated thus :

[Σ(temperature change)] / n
Where n = number of temperature values

Σ Temperature change = Σ difference

Hence,

Σ difference = (-8 + (-1) + 0 + (-1) + 1 + 1 + (-1)) = - 9

n = 7

The mean change in temperature = (-9 ÷ 7) = - 1.285

Hence,

Upper integer values for the mean change = - 1

Lower integer value for the mean change = - 2

Therefore, mean temperature value of - 1.285 lies in between -2 and -1.
