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 How would you interpret the single-sample t test results for the participants who signed by hand? O A. The mean, 12.89, was statistically significantly lower than the population mean, so it is likely that the participants in this sample told experimenters they scored lower than their actual score. O B. The mean was lower than the population mean, but not statistically significant, so the results are inconclusive. O C. The mean was higher than the expected average, so participants likely inflated their roll score. OD. The mean was higher than the population mean but not statistically significant, so the results are
