The Number of Cars Running a Red Light in a Day

question 46

Short Answer

The number of cars running a red light in a day, at a given intersection, possesses a distribution with a mean of 1.7 cars and a standard deviation of 5. The number of cars running the red light was observed on 100 randomly chosen days and the mean number of cars calculated. Describe the
Sampling distribution of the sample mean.
A) approximately normal with mean $= 1.7$ and standard deviation $= 0.5$
B) shape unknown with mean $= 1.7$ and standard deviation $= 0.5$
C) shape unknown with mean $= 1.7$ and standard deviation $= 5$
D) approximately normal with mean $= 1.7$ and standard deviation $= 5$

• A) approximately normal with mean \(= 1.7\) and standard deviation \(= 0.5\)
• B) shape unknown with mean \(= 1.7\) and standard deviation \(= 0.5\)
• C) shape unknown with mean \(= 1.7\) and standard deviation \(= 5\)
• D) approximately normal with mean \(= 1.7\) and standard deviation \(= 5\)
