In a recent year, 64% of all formal complaints to government institutions were resolved. The other complaints were unresolved, discontinued, or not substantiated. A spokesperson for Revenue Canada claims that they had a more positive record. In a sample of 58 complaints received, 42 were resolved (based on Information Commissioner of Canada, Annual Report, 1995-1996). Do the data suggest that more than 64% of complaints to Revenue Canada were resolved? Use the 0.01 level of significance.
Test the given claim, and draw the appropriate graph. Use the traditional method or the P-value method of testing hypotheses (or your instructor may specify which method to use with assigned exercises). Assume that all samples have been randomly selected.
