CSEL gets very crowded when homework is due, or when there is a test for Intro to Data Science. Let T denote the random variable representing the length of time between subsequent arrivals of students. T should follow an exponential distribution (in minutes) with LaTeX: \lambda = 0.2 λ = 0.2 students per minute. How long on average are the intervals between student arrivals?

5 minutes

Step-by-step explanation:

If the mean arrival rate is 0.2 students per minute, the expected time interval between student arrivals, in minutes, is determined by the inverse of the arrival rate:

The interval between student arrivals is, on average, 5 minutes.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
