    Multiple independent variables and common end point

    Can you show a sample of the data. It's not entirely clear to me what you have.

    Very small sample size

    Is it possible? Sure. Will it be useful to fit that model? ....

    One sample or independent samples t-test?

    I don't use SPSS. Sorry.

    One sample or independent samples t-test?

    Your teacher is right. If you do a one sample test and just compare against the sample mean for the UK then you ignore all the variability in the sample for UK.

    Probability of something happening per day when you know the mean per month using binomial distribution

    There is literally no difference between "probability of one car accident per day" and "one car accident in 24 hours". I'm not sure why you modified your formula for that.

    data tranformation

    I'm not sure it would make much sense to do an empirical version of this transformation so that you could do further analysis on it if that's what you're suggesting.

    data tranformation

    Yup. That's basically it although I think their question was mainly on the notation but you covered it. This is a case where we do need to care if Y is continuous or not though (which you mentioned but it deserves an extra special call out here)

    data tranformation

    It was. I even had a response I was going to post once I had time.

    Sample size for destructive testing

    Good luck

    data tranformation

    I don't understand your notation for describing the notation you don't understand. Do you have a link to what you're talking about? Or possibly an image?

    Help with poisson

    Why do you want to use poisson here? That doesn't seem to be an ideal choice.

    How to get amount to pay in order to be fair

    Nah. In a probability problem fair had a much cleaner definition.

    Adding variances and getting standard dev from results

    It's still not clear to me what you're actually trying to calculate the standard deviation of. It sounds like you're not entirely clear on that either. If you don't know what you want it's very hard for me to do anything.

    Adding variances and getting standard dev from results

    What are you looking to find the standard deviation of exactly? Do you want to know what the standard deviation would be if you literally ignored the grouping, considered all the data as a single dataset and then calculated the standard deviation? Or are you interested in what the standard...

    I would. But I almost prefer keeping it around in case they do it again we have their history available.

    Two probability questions. Even HOW to do it would be a huge help

    All of your work for that is correct except for one thing. In both cases where your calculating using the "choose" function you're getting it wrong. 4C4 is 1 and 4C3 is 4. I'm not sure how you're getting your answers of 1/6 and 2 but that seems to be your issue with that problem.

    Two probability questions. Even HOW to do it would be a huge help

    Can you show what you did for the second question, the answer you got, and what you think the correct answer is?

    Two probability questions. Even HOW to do it would be a huge help

    Do you know the law of total probability? Do you know if the binomial distribution?

    Standards déviation

    I hate when people edit out the content of the original post. I'm always tempted to bank the users that do that.

    It was pretty obvious that hlsmith was asking you to explain your terminology. What is DEA? Acronyms aren't universal and can mean different things in different contexts. Also please share what you've tried and why they didn't work.
