Since the question is asking for the relative frequencies of the columns, we assume each row must add to 1.00. Divide the numbers in each row by the total of that row.
.. group 1, column A = 102/(102 +34) = 0.75
.. group 1, column B = 34/(102 +34) = 0.25

.. group 2, column A = 18/(18 +14) ≈ 0.56
.. group 2, column B = 14/(18 +14) ≈ 0.44

A linear regression is done on data the line of best fit is y= 1.25x-6.25. What is the residual for the point (1,1)?

Damm [24]

Answer:

Step-by-step explanation:

Find the predicted y value when x=1:

$\hat{y}=1.25x-6.25\\\hat{y}=1.25(1)-6.25\\\hat{y}=1.25-6.25\\\hat{y}=-5$

Find the residual:

$\text{Residual}=\text{Actual Value}-\text{Predicted Value}\\\text{Residual}=y-\hat{y}\\\text{Residual}=1-(-5)\\\text{Residual}=1+5\\\text{Residual}=6$

Because our residual is positive, this is an indicator that our predicted y value is too low.
