Self-concept can be defined as the general view of oneself in terms of personal value and capabilities. A study of whether visual impairment affects self-concept was reported in the article "An Exploration into Self Concept:AComparative Analysis between the Adolescents Who Are Sighted and Blind in India" (British Journal of Visual Impairment, Vol. 30, No. 1, pp. 31-41) by S. Halder and P. Datta. Independent random samples of sighted and blind Indian adolescents gave the following data on self-concept.

a. At the 5% significance level, do the data provide sufficient evidence to conclude that a difference exists in self-concept distributions between sighted and blind Indian adolescents?
b. Repeat part (a) at the 1% significance level.
