(14) Suppose a researcher investigated the relationship between the number of hours students spent studying and their test scores. The researcher concluded that the data indicate that studying more hours causes students to have better test scores. The data are summarized in the scatterplot below. Scatterplot showing the relationship between the number of hours students spent studying and their test scores. Y-axis represents the test score, ranging from 0 to 100. X-axis represents the number of hours spent studying, ranging from 0 to 18. Data is shown starting just under 40 and just under 80 at 2, slightly increasing to in between 70 and 100 at 16. (a) Do you agree with the researcher's conclusion? Explain
