Answer 1

Answer:

D.There is not sufficient evidence to support the claim because there are not substantially more heads than tails.

Step-by-step explanation:

Using the rare event rule, the assumption that the coin favors heads when​ tossed would only be true if there was a significant gap in the number of heads and the number of tails in the tosses.

Our results are 10 heads and 12 tails. This means that the correct answer is:

D.There is not sufficient evidence to support the claim because there are not substantially more heads than tails.
