Answer:
Step-by-step explanation:
a) The standard deviation is usually preferred over the range because it is calculated from all of the data and will not be impacted as much as the range when they are outliers,and the standard deviation uses all of the data.
b)The IQR sometimes referred to the standard deviation when there is an outlier because the IQR is less sensitive to this features than standard deviation.
that is the IQR is not affected by an outlier,while the standard deviation is affected by an outlier.
c)The advantage of the standard deviation over the IQR is the standard deviation takes into account the values of all observation,while the IQR uses only some of the data.
Answer:
need a pic or the whole thing
I think the answer is <span>x=220</span>
They all have the same slope do it with the equation (y2-y1)/(x2-x1) so if you do it for all of them for example (80-40)/(4-2)=20 and the same answer goes to every single combination.
Hope this helps!
