A researcher wants to determine if the exam scores of the students are dependent on the length of time spent in studying the subject. Ten students in a certain class were taken and the results are shown in the table below where X is the time spent in studying the subject in hours and Y is the examination scores.Which of the following statements is true? If a student spend 2 hours and 45 minutes in studying the subject, then his estimated examination score (in whole number) is 84. For every hour increase in the time spent in studying the subject, its examination score will increase by 7. The time spent in studying the subject and the examination score are not associated at all. There is an inverse linear relationship between the time spent in studying the subject and the examination score.
