Normal distribution: s known and normally distributed population or s known. There is sufficient evidence to support the claim that p > 0.2. TABLE A-3 t Distribution: Critical t Values. There is not sufficient evidence to support the claim that p > 0.2. There is sufficient evidence to support the claim that p > 0.2. So, multiply by (100) to find that a proportion of 73.891 of the population falls below the z-score (0.64.) Therefore. The row and column intersect at (0.73891).
