Question:
The exponential probability distribution can be used to model waiting time in line or the lifetime of electronic components. Its density function is skewed right. Suppose the wait-time in a line can be modeled by the exponential distribution with \(\mu=\sigma=5\) minutes.
(a) Simulate obtaining a random sample of 15 wait-times.
(b) Explain why constructing a \(95 \%\) confidence interval using Student's \(t\)-distribution is a bad idea. Nonetheless, construct a \(95 \%\) confidence interval using Student's \(t\)-distribution.
(c) Use the data to construct a \(95 \%\) confidence interval for the mean using 1000 resamples.

What I have learnt in my 8 years experience of tutoring is that you really need to have a friendly relationship with your students so they can come to you with their queries without any hesitation. I am quite hardworking and I have strong work ethics. Since I had never been one of those who always top in the class and always get A* no matter what, I can understand the fear of failure and can relate with my students at so many levels. I had always been one of those who had to work really hard to get decent grades. I am forever grateful to some of the amazing teachers that I have had who made learning one, and owing to whom I was able to get some extraordinary grades and get into one of the most prestigious universities of the country. Inspired by those same teachers, I am to be like one of them - who never gives up on her students and always believe in them!
