A Temporal Investigation of Crash Severity Factors in Worker-Involved Work Zone Crashes: Random Parameters and Machine Learning Approaches:
Reason:
In the context of work zone safety, worker presence and its impact on crash severity has been less explored. Moreover, there is a lack of research on contributing factors by time-of-day. To accomplish this, first a mixed logit model was used to determine statistically significant crash severity contributing factors and their effects. Significant factors in both models included work-zone-specific characteristics and crash-specific characteristics, where environmental characteristics were only significant in the daytime model. In addition, results from parameter transferability test provided evidence that daytime and nighttime crashes need to be modeled separately. Further, to explore the nonlinear relationship between crash severity levels and time-of-day, as well as compare the effects of variables to that of the logit model and assess prediction performance, a Support Vector Machines (SVM)
What is meant by machine learning approach?
Machine Learning is an AI technique that teaches computers to learn from experience. Machine learning algorithms use computational methods to “learn” information directly from data without relying on a predetermined equation as a model.

Answer:
B.
Explanation:
Based on the information provided within the question it can be said that the Philadelphia Phillies could lower ticket prices to increase attendance, since the quantity supplied exceeds the quantity demanded. On the other hand, if the demand were to exceed the quantity of tickets supplied, then the ballpark would already be filled and the Philadelphia Phillies could keep prices steady or raise them for increased profit.

Answer:
The statement that most demonstrates a negative bias is Statement 4: Most of the immigrants of the early 1900s were criminals from the old country who couldn't be trusted.
Explanation:
The statement that most immigrants were criminals demonstrates negative bias because they are extending this concern to the whole immigrant population. It is not true that all of the immigrants were criminals and yet the person stated that all immigrants cannot be trusted. This is an example of stereotyping the immigrant population and of acting towards them with prejudice. We should try to avoid biased and ethnocentric thinking when we interact with other groups as these stereotypes and assumptions can perpetuate inequalities and discriminatory behavior.
