Here is the question solved in this video:
Suppose you want to test if there is a significant linear correlation between the number of hours spent studying (X) and the exam scores (Y) for a sample of 10 students.
Here's the data:
Hours Studied (X): 2, 7, 6, 3, 1.5, 8.5, 9, 11, 5, 4
Exam Scores (Y): 23, 71, 73, 28, 20, 82, 93, 100, 57, 42
We show you how to use your Casio fx-991-ES Plus Calculator to find the Sample Correlation Coefficient r and the Regression coefficients b0 and b1.
