Two hundred and eighty boys completed a test that measures the distance that the subject can walk on a flat, hard surface in 6 minutes. For each age group shown in the table, the median distance walked by the boys in that age group is also given.RepresentativeAge (Midpointof Age Group)Median Six-MinuteAge GroupWalk Distance(meters)3-5545,36-8585.09-1110668.312-1513.5700.116-1817726.6In USE SALT(a) With x = representative age and y = median distance walked in 6 minutes, construct a scatterplot.yyyy20207507501515700700650650101060060055505505506006507007505506006507007505101520101520Does the pattern in the scatterplot look linear?O The scatterplot shows a curved pattern.O The scatterplot shows no pattern at alI.O The scatterplot shows a linear pattern.
