![2. According to World Health Organization (WHO), the recommended limit for a
noise level inside a classroom is 35 dBA. However, nine out of ten schools fail
to meet this recommendation. A researcher wishes to conduct a study relevant
to the prior information, but as a gap, he decides to include the area (in square
meters) of every classroom and how it could possibly affect the resulting noise
level. He selects 17 classrooms at random, and the noise levels are recorded in
the next slide. Calculate the correlation coefficient and interpret the result.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5923b399-fdee-42a5-be24-1c19a1444214%2F560f6cc5-06d7-4400-98d3-1741051c5e3f%2F6umsc3_processed.png&w=3840&q=75)
