Directions: For each question, be sure to answer each questions in as much detail as possible in the spaces provided. 1. The city of Petersburg has 12,500 registered voters. There are two candidates for city council in an upcoming election: Brown and Stephens. The day before the election, a telephone poll of 500 randomly selected registered voters was conducted. 207 said they vote for Brown, 249 said they’d vote for Stephens, and 45 was undecided. Describe the population the surveyors are really interested in. Give the sample statistic for the proportion of voters surveyed who said they would vote for Brown. The proportion should be a fraction or decimal, not a percent.

Dr. Dorothy Smith gave the students in her geometry class at the University of New Orleans the following question. Is it possible to construct a triangle such that the second angle of the triangle has a measure that is twice the measure of the first angle and the measure of the third angle is 5 times the measure of the first? If so, find the measure of each angle.
