Ophthalmologists require an instrument that can rapidly measure interocular pressure for glaucoma patients. The device now in general use is known to yield readings of this pressure with a variance of 10.3. The variance of five pressure readings on the same eye by a newly developed instrument is equal to 9.8.

Does this sample variance provide sufficient evidence to indicate that the new instrument is more reliable than the instrument currently in use? (Use α = .05.)
