An auditor for a hardware store chain wished to compare the efficiency of two different auditing techniques. To do this he selected a sample of nine store accounts and applied auditing techniques A and B to each of the nine accounts selected. The number of errors found in each of techniques A and B is listed in the table below:

Errors in A	Errors in B
27	13
30	19
28	21
30	19
34	36
32	27
31	31
22	23
27	32

Does the data provide sufficient evidence to conclude that the number of errors in auditing technique A is greater than the number of errors in auditing technique B at the 0.1 level of significance? Select the [Rejection Region, Decision of Reject (RH₀) or Failure to Reject (FRH₀)]. (Hint: the samples are dependent)

a)[t < -1.4, FRH₀]

b)[z < -1.4 and -z < -1.4, FRH₀]

c)[-t < 1.4 and t < 1.4, RH₀]

d)[t > 1.4, RH₀]

e)[t < -1.4 or -t < -1.4, RH₀]

f)None of the above
