Chapter 8.8, Problem 59S

To determine

To calculate: To determine and explain whether a scatter plot of the data for given scenario will show a positive, negative or no relationship

Answer to Problem 59S

Temperature and heating costs are positively correlated

Explanation of Solution

Given information: temperature and heating costs

Calculation:

Given pair of quantities are as follows:

Temperature and heating costs

The above pair of quantities are positively correlated and the correlation is strong.

Heating costs is cost required to heat up the object. More the temperature, more will be the heating cost and vice versa.

Conclusion:

Hence, quantities − temperature and heating costs are positively correlated
