An educational researcher is interested in comparing the reading skills of children in three schoos systems. Inner City, Suburban, and Rural. A random sample of 4 children from each system provided the following reading scores:

Inner City--79-84-74-93
Suburban--90-84-87-95
Rural--79-73-67-78

Assume the samples comes from normal populations with equal variances.

At the 5% significance level, can the researcher reject the hypothesis that the mean reading scores of all children in the three school systems is the same? Formulate and test the appropriate hypotheses. Use the critical value approach.
