Owen has charted the number of hours he studied for each 5th grade math test and the grade he received on each test. Owen's data is listed in the table. Hours Studied Test Score 70 3.5 8 95 6.5 80 2 50 7 85 5 75 6 80 4 65 Represent the data using a scatterplot. On what fraction of Owen's math tests did he have a score of at least 80? Describe the relationship between the number of hours Owen studies and his test score. If Owen wants to score at least a 90, about how long should he plan on studying? Justify your reasoning.
