Using six classes, construct a frequency distribution table for the data in Table 2. List the frequencies, midpoints, relative frequencies (round to 3 places), and the curfrequencies. Please organize your table similar to the Frequency Distribution Table posted under Files in Course Information in your course.23. Using your results in problem 22, construct a frequency histogram. (If you sketch it by hand, please remember you must use graph paper).24. Using your results in problem 22,construct an ordered stem-and-leaf chart for the data set (see Section 2.2).25.

2. The boxplot below represents data collected on some variable of interest. The mean of this data set is 51. The vertical line represents some value which we will call "X". In the table below there are ten numbers, ordered from smallest to largest. For parts a. through f., write down the number that matches the appropriate value from the table. No number will be used more than once, and four numbers will not be used at all. X : 40 45 50 55 60 - 5.9 - 0.63 0.69 5.1 17.8 20.5 48.5 51.9 53.6 56.3 a. Q1 (25th percentile) = b. Median = c.

Question #9 A-D
Suppose a researcher collects data on the air pollution levels, measured in milligrams per cubic meter, for both urban and rural areas in 35 states. The data is plotted with urban air pollution levels on the horizontal axis and rural air pollution levels on the vertical axis. Nevada is an outlier in the ?x‑direction. What must be true about this state? The urban air pollution levels for this state are much higher or lower than the rest of the states in the data set. The rural air pollution levels for this state are much higher or much lower than the rest of the states in the data set. This state is an influential observation. The rural air pollution levels for this state are much higher or lower than other states in the data set that have similar urban air pollution levels. The absolute value of the residual of this state is large.
