1. ### 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...

3. ### 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.
4. ### 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...
5. ### 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 :)
6. ### 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...

8. ### 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...
9. ### 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...
10. ### How many students total are in this class?

The book got 28 students, I got up, when I added up 2+3+4 etc. I got a bigger answer explain please, if I did it wrong. Thank - you in advance
11. ### Statistics: Frequency

I 'am stuck at , what fraction of the shoes were size 4 I know the frequency is missing. The frequencies are 8,9,9,3,1. My thinking you how to add the frequencies and put 4 over it. Explain to me if I'm wrong. Thanks in advance
12. ### B How to Present Statistical Data

<Moderator's note: Moved from a homework forum.> Mass (g) +/- 0.01 grams Drop height (centimeters) +/- 3.00 Shell 53.47 45 No crack 56.78 45 Cracked...
13. ### 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...
