To write:The equation of the median fit line.
a
Answer to Problem 9PPS
The equation of the median fit line is
Explanation of Solution
Given information:refer to the table given above
Calculation:
Here, the data should be divided in three equal sections which in this case would be in the ratio of
Now, let the Store Size be the x-coordinate and the Tubs be the y-coordinate.
Thus, the points for the median fit line are as follows,
X-coordinate | Y-coordinate | X-Median | Y-Median | |
Section-1 | (2100,2225) | (110,102) | 2162 | 106 |
Section-2 | 3135 | 215 | 3135 | 215 |
Section-3 | (3569,4587) | (312,265) | 4078 | 2885 |
Thus, the slope of the Median-Fit Line is,
Therefore, the equation of the Median Fit Line using one point form is,

Explanation of Solution
Graph:
The equation of the line is
c
To calculate:The numberof tubs delivered to the store of size 1500 and 5000 (sq.ft.) respectively.
c
Answer to Problem 9PPS
The numberof tubs delivered to the store of size 1500 and 5000 (sq.ft.) respectively are 48.2 and 380.7
Explanation of Solution
Given information:As derived in the previous part the equation of Median Fit Line is,
Calculation:
putting the values of x in equation we get,
