Question

The New York Choral Society divides male singers up into four categories from highest voices to lowest: Tenor1, Tenor2, Bass1, Bass2. In the table are heights of the men in the Tenor1 and Bass2 groups. One suspects that taller men will have lower voices, and that the varience of height may go up with the lower voices as well. Do we have good evidence that the varience of the heights of singers in the Tenor1 group is greater than the varience in the Bass2 group? Test the hypothesis at 1% level of significance.

Tenor1	69	72	67	72	68	67
	72	75	70	74	67	70
Bass2	71	67	65	70	64	70
	66	75	72	66
