Just read up last night that if SSR=SST then its a perfect linear relationship.
Anyway I am taking a break from this forum for the next 1 month, got alot of work to do, so I'll look forward to bumping into you guys again in July. Just decided that I needed a break as I have been sitting in front of a computer all the time and have no social life as well.

We can disregard quantity in this question.

The probabilistic interpretation: X ~ Bin(n, p) counts the no. of sucesses in n independent Bernoulli trials (with success parameter p) and Y ~ Bin(m, p) counts the no. of successes in m independent Bernoulli trials. So if X and Y are independent, X + Y is counting the no. of successes in m+n independent Bernoulli trials (each with success prob. p), whence X+Y ~ Bin(m+n, p).
Another one you can do similarly:

Received this question from a friend so wanted to share it here.
You roll a conventional die repeatedly. If it shows 1, you must stop, but you may choose to stop at any prior time. Your score is the number shown by the die on the final roll. Consider the strategy: stop the first time that the die shows r or greater.
a) What stopping strategy (i.e. what value of r) yields the greatest expected score?
￼
b) What strategy would you use if your score were the square of the final roll?

It's a geometric distribution but suppose we didn't know that

Which of the following R expressions are logical? (i.e. evaluation of them results in logical objects). Select all that apply.
- exp(x)
- y>=32
- B==’a”
