For four populations, the population variances are assumed to be equal.Random samples from each population provide the following data. 
Using a .05 level of significance, test to see if the means for all four populations are the same.
Population Variances
A measure of the dispersion of all the data points in a population.
Level of Significance
The threshold below which a p-value must fall for an effect to be considered statistically significant, often set at 0.05 or 5%.
