Explanation of Solution
Given information:
Let
The above table shows the normal monthly precipitation (Inches) for San Francisco, California.
Graph:
Interpretation:
Using the graphing utility, the scatter plot for the given data is shown above.
b
To find a quadratic model for the data using regression feature of a graphing utility and to identify the coefficient of determination.
b

Explanation of Solution
Given information:
Calculation:
Using the graphic utility to find the regression,
Insert the data in the table in a grpahic utility to get the following results:
Conclusion:
Therefore, from the above figure, the regression equation for the quadratic model is
c
To draw the graph with the scatter plot from subpart (a) using a graphic utility.
c

Explanation of Solution
Given information:
Graph:
Interpretation:
Using a graphic utility, a parabola is formed when the data is kept on a graph.
d
To observe the graph in subpart (c) and find the month with the least precipitation in San Franciso, California.
d

Answer to Problem 17E
July
Explanation of Solution
Given information:
Refer to the graph in subpart (c).
On observing the graph in subpart (c), it is clear the that the least precipitation has occurred at the point
e
To observe the given table and find the month with the least precipitation in San Franciso, California and compare to that of the option in subpart (d).
e

Answer to Problem 17E
July
Explanation of Solution
Given information:
On observing the table, we find that the precipitation in the month of July is the least with 0.00 inches.
Conclusion:
Also, it is obvious from the graph and the table that least precipitation has occurred in the month of July.
