Answer:
<em>The residual value when x=2 is </em><em>-1</em>
Step-by-step explanation:
The difference between the observed value of the dependent variable and the predicted value is called the residual (e). Every data point has one residual. Lesser the residual value, better the best fit line is.
Mathematically,
Here from the graph,
the observed value is 2, so y=1
the predicted value is 0.5(2)+1 = 1+1 = 2, so
Putting the values,
The correct answer is: Option: A
A. 85, 78, 80, 108, 46, 66, 68, 82, 72, 68
<h2>Step-by-step explanation:</h2>It is given that:
The whisker ranges from 66 to 85.
The box ranges from 68 to 82 with the vertical bar inside the box at 75.
Also,
Also, it is given that:
One dot mark above forty-six.
One dot mark above one hundred and eight.
A)
On arranging the data in increasing order after removing outliers 46 and 108 we have:
66 68 68 72 78 80 82 85
Hence, from this data we have:
Minimum value=66
maximum value=85
As all the values matches the value defined.
Hence, this option is correct.
B)
On arranging the data in increasing order after removing 46 and 108 we have:
66 68 68 70 70 80 82 85
Hence, from this data we have:
Minimum value=66
maximum value=85
As the value of .
Hence, this option is incorrect.
C)
On arranging the data in increasing order after removing 46 and 108 we have:
66 68 72 78 80 80 82 85
Hence, from this data we have:
Minimum value=66
maximum value=85
As the value of do not match.
Hence, this option is incorrect.
D)
On arranging the data in increasing order after removing 46 and 108 we have:
66 68 68 72 78 80 80 85
Hence, from this data we have:
Minimum value=66
maximum value=85
As the value of do not match.
Hence, this option is incorrect.
