In a box and whisker plot, the Median is represented by the line at the center of the box.
So, from the above figures we can see that the Median for the Class Data is around 82 and the median for the Exam Data is around 87. It is clear that the Median of Exam data is higher than the Median of Class Data.
So, the best statement to describe the medians will be the option C. The class median is lower than the exam median. The option A and B are not correct. The outlier does have not have much of a large impact on the median of the data and neither the spread of the data primarily determines its median. Median only depends on the number of values in the data set.
Therefore, the correct answer is option C
Answer:
y = -2.5x +100
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
We need to solve for y
25x+ 10y =1000
Subtract 25x from each side
25x-25x+10y = -25x +1000
10y = -25x+1000
Divide each side by 10
10y/10 = -25x/10 +1000/10
y = -2.5x +100
Answer:
3 to 12 and 1 to 4:
Step-by-step explanation:
3 to 12 would be = 3:12
1 to 4 would be = 1:4
Since ratios can also be fractions, think of it this way. 3:12 as 3/12, and 1:4 as 1/4.
Now, if you simplify, you will see they are equivalent to each other,
3/12 = 1/4
If she studied for 2.3 she would have a total of 11.5 because if she got 5 points per hour you just have to multiply it the number of hours she spent studying. So 2.3 x 5 = 11.5! :-)
