question 73

Short Answer

The state highway department is studying traffic patterns on one of the busiest highways in the state.

A random sample of 64 days gives us a sample mean of 14,205 cars and a sample standard deviation of 1,010 cars. What is the 98 percent confidence interval estimate of μ, the mean number of cars passing the intersection?
