(a) State Ho and Ha and identify the claim.

(b) Determine the critical value, and the rejection region.

determine the critical value from the chi-square distribution table, the alpha level, alpha, and the degrees of freedom

(c) Calculate the test statistic.

(d) Decide whether to reject or fail to reject the null hypothesis.

Then interpret the decision in the context of the original claim.

A social service organization reports that the level of educational attainment of mothers receiving food stamps is uniformly distributed. To test this claim, you randomly select 102 mothers who currently receive food stamps and record the educational attainment of each. The results are shown in the table on Response Frequency, f the right. At o=0.05, can you reject the claim that the distribution is uniform? Complete parts (a) through (d) below.
