According to researchers, a coin flip may not have a 50% chance of landing
heads and a 50% chance of landing tails. In fact, they believe that a coin is
more likely to land the same way it started. So if it starts out heads up, it
is more likely to land heads up. Suppose someone tests this hypothesis with
1,000 flips of a coin where it starts out heads up each time.

a. Describe what the symbol π stands for in this

 b. State your null and alternative hypotheses.

 c. Suppose 52% of the sample of 1,000 flips landed heads
facing up. Verify the validity conditions that allow us to use a theory-based

d. A theory-based test reports a standardized statistic of
1.26. Interpret what this means.

e. A theory-based test reports a p-value of 0.1030. State
your conclusion in terms of strength of evidence and what that means in the
context of the study.
