Question
Chapter 5, Problem 5.20CYS
To determine
To find: The school GPA if one child in this class has IQ score 110.
Expert Solution & Answer
Answer to Problem 5.20CYS
The correct answer is option (b).
Explanation of Solution
Given info:
The given
Reason for correct answer:
Justification:
From the output, it is observed that the corresponding value on the School GPA in y axis to the value of 110 on the IQ test score in x-axis meets the regression line on 7.5.
Reason for incorrect answer:
Option (a): 2 are wrong because the calculated predicted value is 7.5.
Option (c): 11 are wrong because the calculated predicted value is 7.5.
Conclusion:
Hence, the predicted school GPA score is, 7.5.
