Question

We study the number of cars to pass a certain intersection between 11am and 12pm each weekday. We pick 50 weekdays at random, and the average count is 83 cars. Based on analysis of other intersections, the standard deviation is 10 cars.

Answer 1

The question deals with statistical analysis within Mathematics, focusing on the calculation of averages, standard deviations, and the formulation of statistical hypotheses.

Step-by-step explanation:

The student's question falls under the category of Mathematics, specifically within the context of statistics.

In this case, the question is related to understanding the average and standard deviation of the number of cars passing through an intersection, and employing these concepts to make statistical inferences or hypotheses about the data.

We can further break down these concepts into testing testable hypotheses like the average number of vehicles passing being 935 per day and calculating probabilities using normal distribution and Poisson distribution for different scenarios.
