 Author Comment/Response Luis Martinez 10/23/08 8:21pm Hi, I've been given a lab assignment to work at school using minitab. I would much prefer to try this with mathematica but I am not sure how to start. The lab calls for a chi-square distribution but there are more variables in the problem than i know how to use. Can someone point me in the right direction (i'm not interested in a solution to the assignment, just how to use mathematica and the chi-square distribution function. Here is the actual lab for reference: Minitab: We will use Minitab to simulate independent repetitions of an experiment that uses a sample size of n. (a) Simulate 1000 replications of an experiment with n = 10 from a population with a chi-square distribution with one-degree of freedom. This population has a mean µ = 1 and standard deviation σ = 1.414. Select CALC > RANDOM DATA > Chi-Square. Generate 1000 rows of data in columns C1–C10 from the Chi-Square Distribution with 1 degree of freedom. Select CALC> Row Statistics > check “Mean”, Input Variables C1–C10 , Store result in C11 . (b) At this point, we have one-thousand sample means stored in column C11. Each sample mean is the average of n = 10 data points. Select STAT > Basic Statistics > Display Descriptive Statistics. Select the variable in C11. Calculate the theoretical values, µ ¯ X and σ ¯ X for n = 10. Are they close to the sample mean and sample standard deviation in the Minitab output? URL: ,
