Answer:
85
Step-by-step explanation:
The correlation coefficient relates the standarized values of the midterms a final score in this way:
where y is the final score that needs to be found, y^ is the average score on the finals, sy is the standar deviation for the scores on the finals, x is the midterm score, x^ is the average score on the midterms and sx y the standard deviation of the scores on the midterms.
If we issolate y on the equation and solve with the data we have, we get that:
r* \frac{x - x^}{sx}[/tex] = 0.5 * = 1
y = 75 + 1*10 = 85
This means the predicted final score will be 85.
