The table lists brain volumes (cm) and IQ scores of five males. Use the sample data to construct a scatterplot. Use the first variable for the x-axis. Based on the scatterplot, what can be concluded about a linear correlation? Brain volume (cm³) IQ 1170 1068 1348 1028 1204 D 101 94 95 97 114 Construct the scatterplot.

O A. There appears to be a linear correlation. As brain volume increases, lIQ increases. O B. There does not appear to be a linear correlation. As brain volume increases, IQ decreases for a while and then increases. O C. There does not appear to be a linear correlation because there is no general pattern to the data. O D. There appears to be a linear correlation. As brain volume increases, IQ increases for a while and then decreases. O E. There appears to be a linear correlation. As brain volume increases, IQ decreases for a while and then increases. O F. There does not appear to be a linear correlation. As brain volume increases, IQ increases for a while and then decreases.
