Explanation of Solution
b.
To calculate; does the model fit in the data.
b.
Answer to Problem 90E
Solution: Good fit
Explanation of Solution
All of the points seems to be very close to graph of model. Hence, it is a good fit.
c.
To calculate; approximation times when temperature was increasing and decreasing using the graph.
c.
Answer to Problem 90E
Increasing:
Decreasing:
Explanation of Solution
Using the graph to approximate when temperature is increasing and decreasing.
Hence,
