A standard method for analyzing aspirin tablets has a known variance of 20. A sample of 10 aspirin tablets is selected and analysed for the amount of aspirin using a modified method, yielding the following results: 254, 249, 252, 252, 249, 249, 250, 247, 251, 252. Determine whether the precision of the modified method is significantly different from that of the standard method at, alpha(a) = 0.10
