Two suppliers manufacture a plastic gear used in a laser printer. the impact strength of these gears measured in foot-pounds is an important characteristic. a random sample of 10 gears from supplier 1 results in x¯1=289.30 and s1=22.1, and another random sample of 16 gears from the second supplier results in x¯2=321.50 and s2=21. is there sufficient evidence to conclude that the variance of impact strength is different for the two suppliers? use α=0.05. round numeric answer to 2 decimal places. since the test statistic, f0 = enter your answer; since the test statistic, f0 =,
