Ming wonders if there is a relationship between students' practicing music and their average
in math class. She surveys ten of her classmates and asks them their average in math. She
also asks if they sing or play a musical instrument, and if so, how many hours they practice
per week. The scatter plot shows her results. Which statement is true? 1)The data are clustered at 5 to 6 hours of music practice per week.
2)The more time a student spends practicing
music, the lower his or her average in math.
3)The student who practices 3 1/2 hours per week and has an 88 average is an outlier.
4)There is a slight positive association between
hours of music practice and math average
