Answer #1

Hypothesis :

H0 : p = 0.5 vs Ha : p 0.5

We know that if alternate hypothesis (Ha) contains < sign then it is left tailed test.

If alternate hypothesis contains > sign then it is right tailed test

and if alternate hypothesis contains     sign then it is two tailed test.

Here alternate hypothesis contains sign.

Hence it is B) Two Tailed test.

Hope this will help you. Thank you :)
