Is honey a cough remedy? Refer to the Archives of Pediatrics and Adolescent Medicine (December 2007) study of honey as a remedy for coughing. The coughing improvement scores (as determined by the children's parents) for the patients in the over-the-counter cough medicine dosage (DM) group, honey dosage group, and control group are reproduced in the accompanying table.

$$\begin{array}{lrrrrrrrrrrrrrr} \hline \text { Honey } & 12 & 11 & 15 & 11 & 10 & 13 & 10 & 4 & 15 & 16 & 9 & & \\ \text { Dosage: } & 14 & 10 & 6 & 10 & 8 & 11 & 12 & 12 & 8 & & & & \\ & 12 & 9 & 11 & 15 & 10 & 15 & 9 & 13 & 8 & 12 & 10 & & \\ & 8 & 9 & 5 & 12 & & & & & & & & \\ \hline \text { DM Dosage: } & 4 & 6 & 9 & 4 & 7 & 7 & 7 & 9 & 12 & 10 & 11 & & \\ & 3 & 4 & 9 & 12 & 7 & 6 & 8 & 12 & 12 & 4 & 12 & & \\ & 13 & 7 & 10 & 13 & 9 & 4 & 4 & 10 & 15 & 9 & & & \\ \hline \text { No Dosage } & 5 & 8 & 6 & 1 & 0 & 8 & 12 & 8 & 7 & 7 & 1 & 6 & \\ \text { (Control): } & 7 & 7 & 12 & 7 & 9 & 7 & 9 & 5 & 11 & 9 & 5 & & \\ & 6 & 8 & 8 & 6 & 7 & 10 & 9 & 4 & 8 & 7 & 3 & 1 & 4 & 3 \end{array}$$

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

Explain the similarities and differences between each confidence interval for the election poll.

Explain the difference between qualitative and quantitative variables. Give an example of qualitative and quantitative variables

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 $50.1\%$?
