Question

50 points!! will mark brainliest to correct answer!!

Tameka is comparing the batting averages and hits for two teams.

She graphs the data in each table and writes the correct rounded values for a and b as shown below for the regression line mc012-2.jpg.

mc012-3.jpg


Next, she uses the steps below to make the comparison.

Step 1 Write the equation of the trend line for team 1.
y=171.1 x t 66.6
Step 2 Write the equation of the trend line for team 2.
y=197.6 + 73.7
Step 3 Compare the slopes.
The slope for team 2 is greater than the slope for team 1.
Step 4 Therefore there is a stronger association in the data for team 2.

Which explains Tameka’s error?


In step 1, Tameka made an error finding the trend line for team 1.
In step 2, Tameka made an error finding the trend line for team 2 .
In step 3, Tameka compared the slopes incorrectly.
In step 4, Tameka mistakenly based the strength of the association on the slopes.

Answer 1

I think your image for your regression line didn't show up, but judging from what I see, the answer should be:
D) In step 4, Tameka mistakenly based the strength of the association on the slopes.

This is because the strength of the association is not determined by the slope of the regression line, but by how close the data points were to the actual line. The closer the points are to the actual regression line, the stronger the association.
