Let X1, . ..,X11 5'55 Ber {3] for some unknown parameter 9 E (U, 1). Which of the following statistics are also tests? 1 if A occurs [Recall that 1 (A) is the indicator defined as follows: 1(A) = {0 otherwise [Choose all that apply.} _ 21\" _ 1 (in > 0.5) _ 1 (IE; 0.5| > 0.01) _ 1 (ii, 6| > 0.5) _ 1 (Xn is a rational number)
