Question

Two groups of children were given visual acuity tests. Group 1 was composed of 50

children who receive their health care from private physicians. The mean score for this

group was 46.4 with a standard deviation of 6.5. Group 2 was composed of 35 children

who receive their health care from the health department, and had an average score of

25.5 with a standard deviation of 3.6. Is there sufficient evidence for one to claim that, in

low mean score than who receive their health care from private physicians? Use α=​
