Answer:
Option E) 2.68; The regression line under predicts the student's English test score.
Step-by-step explanation:
We are given the following information:
The IQ scores and English test scores of fifth grade students is given by the regression line
where y is the predicted English score and s is the IQ score.
Here English score is the predicted variable that is the dependent variable and the IQ score is the independent variable and plays the role of predictor.
An actual English test score for a student is 65.7 with an IQ of 96. We have to predict the English score with the help of regression equation.
Predicted or interpreted English score =
Thus, predicted English score is 63.0216.
Observed value of English score at IQ 96 is 65.7
Residual = Observed value - Predicted value
=
Since the predicted value is less than the original or observed value we can say that the regression line under predict the English score.
Option E) 2.68; The regression line under predicts the student's English test score.
The inequality is,
we have given that the solution set
2, 1, 3. 9, 4 2001. 3, 4, 0, 2. 6 1. 1, 1. 5, 19. 7, 8. 2 11, 1, 48. 5, 7.
here we have given that all the values of x are positive and
Which is the smallest point in above set?
0
and
Which is the highest point in the above set?
2001.3
Therefore,
we have a=0 and b=2001.2
Our equality lie in a and b
Therefore,
Plug the value of a and b we get
Therefore we get the inequality is,
