Need probability and statistics !
a high school teacher recorded the number of hours each of his students spent on a social networking website in a particular week and related this with their scores on a math test they took at the end of the week. the data is represented in the scatter plot.
qualitatively evaluate the information in the scatter plot. an acceptable estimate for the graph's correlation coefficient could be (0.15, 0.50, 0.75, 1.00). based on the data, we can conclude that the time students spent on the social networking website had a (strong and positive, strong and negative, moderate and negative, weak or insignificant) effect on their performance on the test.
