Process 1 has n=21, variance 0.15

Process 2 has n=25, variance 0.33

A batteries manufacturer uses two different production processes 1 and 2 . There is some degree of variability (in voltage), and an engineer claims that process 1 is better (in the sense of having smaller variance) than process 2, there are two samples taken, test the engineer's claim at the 5% level of significance.
