### Compute expectation of a random variable given the density function

The probability density function is given by: $f(t)= (8-t)^2 /9$ for $5 \le t \le 8$ Compute the mean daily CPU time. Hence state the mean of a new variable $W=T+12$ hours. For this question, ...

### Stats test which test of the NULL that a distribution is uniformally distributed

I'm looking for a statistical test which tells the probability that a given sample comes from a uniform distribution. Shapiro test wether a sample comes from a normal distribution. I'm looking a ...

### Sample changing distribution

I have the following process: I have N buckets in front of me, $M$ of which are filled with water (the other ones are empty). I pick one of them (consider uniform distribution) and empty it (so ...

### Last-digit test and probability

I have done a last-digit test on a draw of numbers between 1 og 370. Team A drew 64 numbers from the pool, and the last digit of those numbers spread out like this: Digit: 0 1 2 3 4 5 6 7 8 9 ...

### How to find the expected distance between two uniformly distributed points?

If I were to define the coordinates $(X_{1},Y_{1})$ and $(X_{2},Y_{2})$ where $$X_{1},X_{2} \sim \text{Unif}(0,30)\text{ and }Y_{1},Y_{2} \sim \text{Unif}(0,40).$$ How would I find the expected ...

### Uniform Random on $(-\infty,\infty)$

Imagine picking a 1 when any real number is equally likely. What is the pdf? Does this idea have a known use? What is its name? There could be a use for a uniform random real number. It could end ...

### How do I test for a symmetric distribution?

I collect numbers from generators that yield different ranges of whole numbers with an unknown distribution. I want to estimate the mean of the numbers outputted by this generator. I'm convinced the ...
