Panic Attacks and Exponential Distribution

It has been demonstrated that the time until a panic attack is experienced by students during a statistics exam can be modeled as an exponential distribution with λ equal to .037^-1 minutes.

a) What is the probability that a student taking a statistics exam will experience his/her first panic attack within the first 10 minutes of the exam?

b) What is the probability that a student will not have a panic attack during this exam? [Assume you have exactly 1 hour and 15 minutes to complete the exam.]

c) What is the expected time before a student experiences his/her first panic attack?

Solution Summary

This solution used the exponential distribution to determine the probability of a panic attack occurring in the first 10 minutes, not occurring the whole exam and the expected time before a student experiences a panic attack. All steps are shown in an Excel file.
