Question

Suppose the entering freshmen at a certain college have a mean combined application test score of 1225​, with a standard deviation of 120. in the first​ semester, these students attained a mean gpa of 2.64​, with a standard deviation of 0.58. a scatterplot showed the association to be reasonable​ linear, and the correlation between application test score and gpa was 0.44. what combined test score would you predict for a freshmen who attained a​ first-semester gpa of 2.9​?suppose the entering freshmen at a certain college have a mean combined application test score of 1225​, with a standard deviation of 120. in the first​ semester, these students attained a mean gpa of 2.64​, with a standard deviation of 0.58. a scatterplot showed the association to be reasonable​ linear, and the correlation between application test score and gpa was 0.44. what combined test score would you predict for a freshmen who attained a​ first-semester gpa of 2.9​?

Answer 1

The enrollees of a particular university have an average application test score of 1225 with a standard deviation of 120. In the first semester, the average number of students was 2.64, the standard deviation was 0.58. The scatter plot showed that it was rational linear and the correlation between application test score and gpa was 0.44. Predictive test score for freshmen who achieved the first sem
