A) +1.00 should be used
B) .05 should be used

The t ratio for establishing a confidence interval at .95 (95%) typically corresponds to an alpha level of .05, which represents the probability of rejecting the null hypothesis when it is actually true (Type I error). This is because the confidence level (95%) and alpha level (.05) are complementary, adding up to 100%.
