Body temperatures for the healthy adults are traditionally said to be 98.6 degrees. To test this traditional theory, 20 healthy adults were randomly chosen and their body temperature measured. Their mean was X = 98.997 with the standard deviation of s = 0.803. To test hypotheses H0: Mu = 98.6 versus H1: Mu is not equal to 98.6, the test statistics was calculated to be 2.211. In order to make the decision about H0, what t value from t table must the test statistic 2.211 be compared to if alpha = 0.05?
A. 2.093
B. 2.539
C. 1.729
D. 2.086
E. 1.725
