The analysis of variance table for a study of the distance between the pupils of the eyes is shown in Table 15.19:

(a) There were 34 observations;

(b) There is good evidence of an ethnic group difference in the population;

(c) We can conclude that there is no difference in inter-pupil distance between men and women;
