Answer with explanation:
The Data Set is→ 10,12,2,4,24,2,7,7,9
Arranging the data in ascending order
2,2,4, 7,7,9,10, 12, 24
Number of observation is odd,
So, Median
5th Observation = 7
=First Quartile of data set that is from first variate to Median value
={2,2,4,7,7}
So,
=Third Quartile of data set that is from last variate to Median value
={7,9,10,12,24}
So,
Minimum value in data set = 2
Maximum value in data set = 24
Plotting the Box plot
Option C , is correct Box plot.
Given:
The graph of two lines.
To find:
The slope of each line and check whether they are same or different.
Solution:
If a line passes through two points, then the slope of a line is:
From the graph 1, it is clear that the line passes through the points (2,175) and (3,165). So, the slope of first line is:
The slope of first line is 10.
From the graph 2, it is clear that the line passes through the points (1,175) and (2,165). So, the slope of first line is:
The slope of second line is 10.
Therefore, the slopes of both lines are same, i.e. 10.
