Answer:
The difference in minutes of median collection times before and after the well was installed is: 25
Step-by-step explanation:
Before--
Clearly after looking at the whisker-box plot we could observe that the middle line in the box represents the median of the data.
Hence we have :
Median(M)=53
After--
Similarly looking at the box-whisker plot we could observe that the line in the box is at 28.
Hence, Median of the box after installing the well is(M'): 28
Hence,
The difference in Median is calculated as:
M'-M
= 53-28
= 25
Hence, the difference in minutes of median collection is:
25 minutes.
