The GPA of the student who scored 63 in the performance test is 2.394.
Given, a researcher analyzed data using linear regression correlating a performance test and GPA and calculated a slope of 0.028 and y-intercept of 0.63.
we have find the GPA of a student who scored 63 in the performance test.
Let the score of the student in performance test be, x
and the GPA of the student be, y
So, y = mx + c
as, m = 0.028 and c = 0.63
y = 0.028x + 0.63
at x = 63
y = 0.028×63 + 0.63
y = 2.394
So, the GPA of the student who scored 63 in the performance test is 2.394.
Hence, the GPA of the student who scored 63 in the performance test is 2.394.
