For a better understanding of the explanation provided here, please find the diagrams in the two files that have been attached.
As can be clearly seen from the diagram, PR and QS are the diameters of the circle and they intersect each other at the centre, O of the circle.
The angle these diameters make at the point of intersection O is 90 degrees.
If Margot joins the points P,Q,R and S which are on the circumference of the circle, then we will get a square with sides PQ, QR, RS and SP as shown in the second diagram.
Thus, the correct option is Option A.
Given:
The data set is
10, 10, 11, 12, 13, 13, 13, 14, 14, 15, 15, 15, 16, 17, 17, 17, 35
To find:
Effect on mean, median, range after removing the outlier, 35.
Solution:
We have, the data set
10, 10, 11, 12, 13, 13, 13, 14, 14, 15, 15, 15, 16, 17, 17, 17, 35
Mean of the data set is 15.12.
because n=17, which is odd.
Median is 14.
Range is 25.
After removing the outlier, 35, the data set is
10, 10, 11, 12, 13, 13, 13, 14, 14, 15, 15, 15, 16, 17, 17, 17
Mean of the new data set is 13.875, which is less than 15.12.
because n=16, which is even.
New median is 14, which is same as original median.
So, the new range is 7 which is less than 25.
Therefore, the mean of the data set will decrease, the median of the data set will not change, the Range of the data set will decrease.
