Answer

Answer 1

The plot is attached

The range of the temperatures is 12

How to find the range of the temperature

Range refers to the difference between the maximum and minimum values in a dataset. It provides a measure of the spread or variability of the data. Mathematically, the range (R) is calculated as follows

R = maximum value - minimum values

from the table

R = 16 - 4

R = 12
