Q1. A psychologist conducted a study on the relationship between introversion and shyness. The values re results for scales of introversion and shyness. High positive scores on each scale indicate high ntroversion or shyness; and high negative scores indicate low introversion or shyness. Data collected rom 10 people as follows: Introversion 4 -7 -1 0 6 7 -4 -9 -5 8 Shyness 11 -7 -1 -3 0 7 -1 -8 -1 5 a) Compute the correlation coefficient relating introversion and shyness scores. Find the regression equation which predicts introversion from shyness. b) c) What introversion score would you predict from a shyness score of 7?
