The number of cars running a red light in a day, at a given intersection, possesses a distribution with a mean of 2.92.9 cars and a standard deviation of 55. 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 meanequals=2.92.9 and standard deviationequals=0.50.5 B. shape unknown with meanequals=2.92.9 and standard deviationequals=55 C. approximately normal with meanequals=2.92.9 and standard deviationequals=55 D. shape unknown with meanequals=2.92.9 and standard deviationequals=0.5
