### Grouped Frequency Distribution and Frequency Polygon#### Data Given:- Test Scores: 83, 92, 91, 86, 90, 97, 93, 81, 81, 95, 82, 85, 80, 92#### Instructions:(a) Complete the grouped frequency distribution for the test scores. Note that the class width is 5.**Grouped Frequency Distribution Table:**| Test Scores | Frequency ||----------------|-----------|| 78.5 to 83.5 | || 83.5 to 88.5 | || 88.5 to 93.5 | || 93.5 to 98.5 | |(b) Using the classes from part (a), draw the frequency polygon for the data. Label each class with its midpoint.**Frequency Polygon Explanation:**- A frequency polygon is a line graph that displays the frequencies of different classes.- The x-axis represents the test scores, segmented by the midpoints of each class.- The y-axis represents the frequency of each class.- Points are plotted at the midpoints of each class and connected with straight lines.**Visual Description:**- The graph has axes labeled "Frequency" and "Test scores."- Midpoints of classes are marked on the x-axis.- Frequencies are plotted starting from the first class midpoint onward. These instructions help visualize data trends using a frequency polygon, and properly organize data using a grouped frequency distribution table.

Given data, Sort the data in ascending order 80,81,81,82,83,85,86,90,91,92,92,92,93,95,97

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.
