**Observations on Degree of Polymerization**An article provided the following observations on the degree of polymerization for paper specimens, where viscosity times concentration fell in a specific middle range:- Observations: 415, 420, 421, 422, 426, 427, 432, 434, 437, 438, 446, 447, 450, 452, 457, 463, 464**(a) Boxplot Construction**A set of four boxplots is depicted, each representing the same data. The boxplots show the distribution of observations in terms of their quartiles, median, and potential outliers.**Features to Comment On:**- There is one outlier.- The data is strongly skewed.- The data appears to be centered near 428.- There are no outliers.- The data appears to be centered near 438.- There is little or no skew.**(b) Evaluation of Normal Distribution**- Is it plausible that the sample observations were selected from a normal distribution? - Options: Yes / No**(c) Confidence Interval Calculation**- Task: Calculate a two-sided 95% confidence interval for the true average degree of polymerization. Answers should be rounded to two decimal places.**Questions:**1. Does the interval suggest that 440 is a plausible value for the true average degree of polymerization? - Options: Yes / No2. Does the interval suggest that 456 is a plausible value? - Options: Yes / No**Graph and Diagram Explanation:**The boxplots display the central tendency, variability, and potential outliers within the data set. Each plot visually represents the quartiles and the overall spread of the data, allowing for interpretation of skewness and the presence of any anomalies.

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.
