Question: A group of 8 unrelated patients with retinitis pigmentosa (RP) were identified with a distinct point mutation in the gene coding for rhodopsin. The mutation corresponds to a single amino-acid substitution in rhodopsin protein. Their ocular findings were compared with 140 unrelated RP patients without the mutation. The results are given in table for in ( visual field area)

Mean sd n

Mutation absent 7.99 1.32 140

What test procedure can be used to test if the variances of the two groups are the same or not? Implement the test and report the result.
