H0 is p = 0.45 and H1 is p ≠ 0.45. What type of test will be performed?
A. Two-tail testing of a proportion
B. One-tail testing of a proportion
C. One-tail testing of a mean
D. Two-tail testing of a mean
** I'm stuck between A & D. I chose those because two-tailed testing does not specify the departure from H0 in a particular direction and is written with the ≠ over < or >, which is the one tailed test hypothesis.
I narrowed it down between the two answers I picked and chose A, though I'm unsure if it's correct.
