A random sample of seven statistics students were taken from the StudentSurvey dataset. The Math and Verbal
Question:
A random sample of seven statistics students were taken from the StudentSurvey dataset. The Math and Verbal SAT scores for the seven students are shown in Table A.9. We are interested in predicting scores on the verbal section using scores on the math section.
Table A.9
Math ................Verbal
720 ....................450
650 ....................530
670 ....................680
660 ....................680
550 ....................560
620 ....................600
680 ....................670
(a) Use technology to plot the data with a regression line to predict verbal scores based on math scores.
(b) Use technology to find the correlation between these seven verbal and math scores.
(c) Based on this sample, is it reasonable to use a regression line to predict verbal scores using math scores? Explain your answer using what you have found in (a) and (b).
