Johnson and Leone describe an experiment to investigate the warping of copper plates. The twofactors studied were temperature and the copper content of the plates. The response variablewas a measure of the amount of warping. The data are as follows:Temperature (°C)5075100Copper Content (%)40 60 80 100172012916122117 2116 242118131821ZZFEHERRE23222717 273130232931122523232822125Source: Applied Statistics and Probability for Engineers, 6th Edition, Douglas, C.

Q1. A psychologist conducted a study on the relationship between introversion and shyness. The values are results for scales of introversion and shyness. High positive scores on each scale indicate high introversion or shyness; and high negative scores indicate low introversion or shyness. Data collected from 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. b) Find the regression equation which predicts introversion from shyness. c) What introversion score would you predict from a shyness score of 7?
