Employ the stem-and-leaf plot or dot plot to list the actual data entries. What is maximum data entry? What is the minimum data entry?

For the stem-and-leaf plot below, what are the maximum and minimum entries?

A set of 25 cards is randomly placed face down on a table. 15 cards have only the letter A written on the face, and 10 cards have only the letter B. Patrick turned over 1 card. What are the odds of this card having the letter B written on its face?

The numbers 1 through 52 are written on individual cards and placed face down. If you draw one of the cards, what is the probability that it will have a number less than 13 on it? Explain how you arrived at your answer.

A political pollster is conducting an analysis of sample results in order to make predictions on election night. Assuming a two-candidate election, if a specific candidate receives at least $55\%$ of the vote in the sample, the candidate will be forecast as the winner of the election. If you select a random sample of $100$ voters, what is the probability that a candidate will be forecast as the winner when the population percentage of her vote is $50.1\%$?

A pollster wants to sample $500$ voters in a town to ask them who they plan to vote for in an upcoming election. Describe a sampling method that would be appropriate in this situation. Explain your reasoning.
