I took a Statistic class in Summer-II 2025 and my final average was 88 so I got ‘B’ grade as long as I get passing grade ‘C’ grade I would be happy.
Now I have to study other statistics books to cover six important chapters were not covered from our class textbook in the class by our instructor for different reasons.
I had few rude and mean female students and some of them were register nurses in my class and I did not say anything to them except I report them to the class instructor.
Generation Z loves few chapters to be cover and get ‘A’ and degree and get a job and then be fired.
I am learning Poisson Distribution & a lot more now.
Example Problem
If a store gets an average of λ=4 customers per hour, what is the probability exactly k=2 customers arrive in the next hour?
P(X=2) = (e^-4 * 4^2 ) / (2!2) = 0.1465
or 14.65%
As λ increases (like 10), the shape becomes more symmetric and starts looking like a normal curve.
