b) Consider the longer research article written by the European research team.
i. In the Results section of the paper, of the 350,757 coin flips, report the number of those coin flips that landed on the same side as when the coin was launched.
ii. Then, by hand, show how to compute, to three decimal places, the sample proportion of flips which landed on the same side as when the coin was launched.
iii. In the Abstract of the paper, report the 95\% credible interval (CI) for the proportion of coin flips that would land on the same side as when the coin was launched.
iv. Given your answer to questions ii) and iii) above,
\begin{itemize}
\item Show, by hand, how to compute the MOE that would be added onto your answer in part ii) to obtain the upper end of the CI from part iii).
\item Show, by hand, how to compute the MOE that would be subtracted from your answer in part ii) to obtain the lower end of the CI from part iii).
\end{itemize}
