Question

WHAT IS THE DIFFERENCE IN MINUTES OF MEDIAN COLLECTION TIMES BEFORE AND AFTER THE WELL WAS INSTALLED

Answer 1

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.
