Suppose a polling agency reported that 45.7% of registered voters were in favor of raising income taxes to pay down the national debt. The agency states that results are based on telephone interviews with a random sample of 1033 registered voters. Suppose the agency states the margin of error for 99% confidence is 4.0%. Determine and interpret the confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt.

Kelly was asked to determine whether △KLN is congruent to △MNL. She noted that KL ≅ MN, LM ≅ KN, and that the three pairs of corresponding angles are congruent. She said that this is only five pairs of congruent corresponding parts, so it is not possible to conclude that △KLN is congruent to △MNL. Do you agree with Kelly's reasoning? Complete the explanation.
