Assume that you are conducting a small sample Mann-Whitney U test where n1 = 14 and n2 = 16 and that U1 = 98. Assuming that U1 has been found correctly, what is the value of U2?
A) 112
B) 126
C) 224
D) Insufficient information to determine U2.

U2 can be calculated using the formula U2 = n1*n2 - U1, where n1 and n2 are the sample sizes of the two groups, and U1 is the U statistic for the first group. Here, n1 = 14, n2 = 16, and U1 = 98. Thus, U2 = 14*16 - 98 = 224 - 98 = 126.
