Step-by-step explanation:
12/15 = .8
subtract from 1
gives you .2
convert to a percentage

This question is incomplete, the complete question is;
Suppose John is a high school statistics teacher who believes that watching many hours of TV leads to lower test scores. Immediately after giving the most recent test, he surveyed each of the 24 students in his class and asked them how many hours of TV they watched that week. He then matched each student's test grade with his or her survey response. After compiling the data, he used hours of TV watched to predict each student's test score. He found the least-squares regression line to be y" = -1.5x + 85.
He also calculated that the value of r, the correlation, was -0.61.
what is the correct value of the coefficient of determination R² and give a correct interpretation of its meaning
Answer:
Interpretation of coefficient of determination R² = 0.3721
R² = 0.3721, meaning 37.21% of the total variation in test scores can be explained by the least square regression line
Step-by-step explanation:
Given the data in the question;
the least square regression line is;
y" = -1.5x + 85
the correlation coefficient r = -0.61
Now, the coefficient of determination R² is square of correlation coefficient r
R² = -61²
R² = 0.3721
The line plot that correctly represents the given data set is: line plot C.
<h3>What is a Line Plot?</h3>
On a line plot, the frequency of a data points is represented using "x" as many times as the data points appear in the data set.
The data point with the highest frequency is 11¼ which is also 11⅛. And they appear 4 times in the given data set.
So, the line plot that correctly shows the data is: line plot C.
