Illustration. 21.22. Comment criticaly on the following state- ments: (a) Road accidents resulted in 4513 deaths in 1958 and 5250 in 1967 while the number of women drivers increased in the period. Hence women make bad drivers. (b) Of 300 persons inoculated against influenza during the epide- mic only 12% were affected. This shows a marked improvement com- paring with the remainder of the population for which the equivalent igure was 28%.

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?
