To find: the predicted increase in temperature if 5 chirps increase per minute
Answer to Problem 9PT
Option (b) is the correct one.
Explanation of Solution
Given:
(a) 13°F
(c) 25.2°F
(e) 41.7°F
(b) 16.5°F
(d) 28.5°F
Calculation:
Here x is the number of chirps per minute and
According to the definition of slope, b. there will be 3.3 units of change in temperature for a unit increment in number of chirps per minute.
Suppose there is an increase of 5 chirps per minute.
We know that, for a unit increment there will be 3.3 units of increment in temperature. Then for 5 units of increment in X values, there will be
That is, the predicted increase in temperature for an increase of 5 chirps per minute will be
Conclusion:
Therefore, the predicted increase in temperature is 16.5°F
