A political newspaper, Politically Sound, is interested in the distances voters in Rising Falls County live from their nearest polling station. Politically Sound has hired you to estimate the population mean of all such distances for voters in this county. To estimate this population mean, you select a random sample of 17 Rising Falls County voters and record the distance (in km) each voter lives from their nearest polling station. Assume the population is approximately normally distributed. Based on your sample, follow the steps below to construct a 99% confidence interval for the population mean of all the distances voters in Rising Falls County live from their nearest polling station. (If necessary, consult a list of formulas.) (a) Click on "Take Sample" to see the results for your random sample.

Suppose there are 5 students in a room. The mean age is 19.8 years, and the median age is 19. If the youngest person leaves and is not replaced by another person, what happens to the mean and the median? O The mean and median increase. The mean increases, and the median either increases or stays the same. The mean increases, but it is impossible to determine whether the median increases, decreases, or stays the same. The mean increases, and the median stays the same. The median increases, and the mean either increases or stays the same.
If you recieved the data set {9, 16, 10, 20, X} and you knew the median was 15, what could you say about X? O 10 < X < 18 OX = 14 O11 < X < 17 OX = 15 ONone of the above.

A researcher is testing Xanax and uses a focus group where individuals are assigned to one of two groups and different doses of Xanax. He then gets the participants to learn a list of 20 numbers and three days later sees how many they can recall. In the experiment the dependent measure is simply the number of numbers recalled by each participant. What type of variable is this? a. Nominal b. Ratio c. Interval d. Ordinal
