Brain volume 1007 Listed below are the brain volumes (in cm" ) of twins and the corresponding IQ score. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using a= 0.05. Is there sufficient evidence to conclude that there is a linear correlation between brain volume and IQ scores? Q score 960 96 1030 90 102 1288 Brain volume 86 1 171 86 1278 1076 101 1058 104 1079 Full Data set Q score 10 1062 1104 104 1037 96 1072 92 1343 97 128 87 95 1434 1028 127 What are the null and alternative hypotheses? 85 1104 96 1200 114 163 113 O A.
