A researcher wishes to determine if the average noise level (in decibels) in a classroom affects the academic performance of learners. She decided to observe several classes, obtained the average noise level occurring in each class, and collected the average score of all 40 students. The average scores of 67.29, 57.88, 86, 72.81, 68.33, and 52.91 have been recorded with the corresponding noise levels: 81.54, 65.22, 73.49, 56.79, 90.61, and 86.09. What is the intercept ofY? Round your answer to two decimal places. Do not place any unit.

Correlation and regression is the lesson
