Hand-signature condition: (M = 12.89, SD = 3.98), t (27) = - 0.14, p = 0.88

E-signature condition: (M = 14.97, SD = 5.05), t (30) = 2.17, p = 0.03

What is a possible interpretation supported by this pair of single-sample t test results?

a. Signing by hand and signing by e-signature carry the same psychological weight, because there was not evidence of dishonesty in either group.

b. There was evidence that participants were dishonest in both conditions; so, we can conclude that some people are dishonest whether they sign by hand or e-signature.

c. In both cases, the results were not significantly significant; so, we cannot conclude that participants, in general, were dishonest in either group.

d. There was not evidence that those who signed by hand were cheating; however, there was evidence that participants in a group that provided e-signatures cheated.
