In Class:
NJ reviews memoryless property of the exponential distribution from the end of class last time.
P(X>14|X>7) is the same as P(X>7)
P(X>10|X>6) is the same as P(X>4).
With this in mind, when/for what kind of products is an exponential distribution a good or bad choice for modeling time until failure or time until arrival? Consider, for examples:
a computer (time until failure)
a lightbulb (time until failure)
a rural intersection (time until arrival)
Which would be better: an appliance that was made in the 1980's versus an appliance that was made in the 2020's?

Dear N.,
How are you doing? Some students in my data science class are interested in organizing a new Data Club on campus. The club is intended for students who are interested in anything related to data, including data science, analytics, visualization, AI/ML, research, and real-world applications of data across different disciplines.
Currently, the students are looking for members as well as students who may be interested in taking one of the five leadership positions in the club.
The club hopes to organize activities and events in the future, such as:
Inviting guest speakers from different fields to discuss real-world data problems
Organizing workshops and discussions on data analysis
Supporting interdisciplinary collaboration and small research projects
Creating opportunities for students to explore careers and applications related to data
I was wondering if you know any students who might be interested in participating, either as general members or as part of the leadership team, please feel free to recommend students for the leadership position.
Here is the interest form:
Please feel free to share this with students who may be interested (Ideally before end of this week so that we can set up the club before end of the semester)
Thanks!
