# F test: Five step approach

A random sample of five observations from the first sample resulted in a standard deviation of (12). A random sample of seven observations from the second sample gave a standard deviation of (7) at the (.01) significance level. Is there more variation in the first population? And is the null hypothesis rejected or not, and why? (ANOVA Test)
