1. ### t, Z and sigma again

The mathematical justification is covered in almost all mathematical statistics textbooks. Requires a decent amount of math background to derive the results though.
2. ### Conditional probability

Which values for X satisfy both X ≥ 1 and X ≥ 2?
3. ### What is this time series coding doing

Let's be clear. I explained what the () surrounding the entire code chunk was doing. I didn't mention the square brackets at all. Which were you asking about
4. ### What is this time series coding doing

I find it odd that you typed that out instead of copy/pasting. You missed the closing parenthesis on each of the quotes. But to answer the question by wrapping everything in parenthesis it will automatically print the results. Typically if you store a result into a variable you don't...

6. ### Problem with package

So monthdays is a function. So you need to supply it an argument (or at least call the function somehow). I really don't know what you were trying to do with your code. Can you explain in plain words what you were trying to achieve?
7. ### Playing Cards Probability

Must have got too excited from all the math
8. ### Hayes Process V3.3 Model 89 in SPSS V25

The attachment would be more helpful if it existed I think
9. ### Observational Study

Can we make your question more vague
10. ### Multiple Linear Regression: to split or not the data

In your one model approach did you include the gender*age interaction term?
11. ### CI from normal distribution using indicator random variables

Have you learned about the continuous mapping theorem? https://en.m.wikipedia.org/wiki/Continuous_mapping_theorem
12. ### Problem with package

What is the structure of monthdays?
13. ### 1

I would love to hear your reasoning for asking about why you should or should not use the Poisson distribution.
14. ### Simple question. Type of data?

Yeah... entirely ordinal. Just because somebody attaches numbers to something doesn't make it continuous.
15. ### Absolute dumbest question so be gentle

That depends on what your goal is.
16. ### Absolute dumbest question so be gentle

Do you want an overall margin of error of 2% or do you want the moe to be 2% within each district

Not allowed.
18. ### Moving away from p-values

Sure. I remember you too. You're the kid that pooped their pants right.
19. ### Moving away from p-values

Not sure what you're getting at but you're wrong. But thanks for actually using quote tags for the first time.
20. ### Moving away from p-values

You've been here almost ten years. You've definitely seem people use quote tags before. http://www.talkstats.com/help/bb-codes/
