Claim: A coin favors heads when tossed, and there are 15 heads in 28 tosses. Which of the following is correct? O A. There is not sufficient evidence to support the claim because there are substantially more heads than tails. OB. There does appear to be sufficient evidence to support the claim because there are not substantially more...

Make a decision about the given claim. Use only the rare event rule, and make subjective estimates to determine whether events are likely. For example, if the claim is that a coin favors heads and sample results consist of 11 heads in 20 flips, conclude that there is not sufficient evidence to support the claim that the coin favors heads (because it is easy to get 11 heads in 20 flips by chance with a fair coin). Claim: The mean...
