Flip a coin 30 times and record the results. A fair coin should land on heads 50% of the time, which is the claim that we will use for our hypothesis.

My results after flipping the coin:
17 heads and 13 tails

My hypothesis would be:
HO: p=0.5
Ha: p not = to 0.5
Where p represents the proportion of heads.

Please help solve by showing each step.
