    Labwork Statistics help: Average of averages

    I have done the experiment, and have a lot of data. For each data point (we have five), we did ten repetitions, for which we need to do video analysis. The analysis works frame by frame and gives a velocity between each frame. So, to get the value of one repetition, we already need to calculate...

    Statistics: Prove following theorem by expressing all the binomial coefficients in terms of factorials

    I really don't know what to do for this problem. I looked at similar threads but couldn't seem to grasp the idea of it. I would like help on how to start.

    I What are the statistics of probability of dying today vs age?

    I don't intend to sound macabre, but I was having this thought if I have to quantify the probability of someone dying given his age (in days) how would I go about quantifying that with a minimal accuracy (ok if it's not accurate but I just need some number with days). Has anyone ever worked out...

    B Statistics Help : Hypothesis Testing

    Answer : I understnad why x(< or = ) 2 but I do not understand why we use 16 instead of 17 for the second range? When P(X>=16) > 0.005(which is the level of significance). Thank you for all the help given :)

    Confidence intervals for ratios of variances and other confusing stats

    Now I don't really know much about the subject, I'm primarily just peaking into my textbook to see how to solve this or that exercise. I believe I can figure out how to solve the third question. However I couldn't find how to solve the first two. I know how to find a 95% confidence interval for...

    Courses Taking statistics courses as a physics major

    Hi, I am currently a second year physics major. I have recently thought about taking statistics/probability courses as electives for the upcoming semester. However, I don't know what types of statistics/probability classes will help me in my physics education. I am not particularly interested in...

    A Kolmogorov-Smirnov Test

    Hi all, I have some doubts regarding the Kolmogorov test: I made a simple c++ program generating two samples of random numbers following a Landau distribution (I used the "hit and miss" method). I made the Kolmogorov test, in order to check the randomness of the generator, but I'm having some...

    I Mixing of regatta competitors

    Dear all, we are organizing a regatta, there are 12 competing crews and we have six boats. Therefore the regatta is organized in so-called fleets, each consisting of two races at which six crews (using the six available boats) are participating. We assume to be able to race 10 to 15 fleets...
