Given the 7 different samples with mean and variance for each group. What can I use to tell if these samples from the same population with 0.05 and 0.01 significance level?
Sample Mean Variance A 50 5 B 47 4 C 52 5 D 51 6 E 49 5 F 52 4 G 49 6
Based on the give data, I calculated F statistics of value 53.72.
Given the the F data, how would you conclude that these samples are drawn from the same population? Is the conclusion the same for the both for 0.05 and 0.01 levels of significant?
I am trying to follow this example: http://en.wikipedia.org/wiki/F-test#One-way_ANOVA_example
but the problem is that I don't have the individual observation to calculate the within-group sum squares. I only have the mean, variance and sample size(10) data. Any ideas how I could approach this?
