# Question: We want to use a 0 05 significance level to test

We want to use a 0.05 significance level to test the claim that a coin favors heads, and sample data consist of 7 heads in 8 tosses. We can’t use the normal approximation method because we violate the requirement that np ≥ 5 and nq ≥ 5. Use the binomial probability distribution to test the claim.
