Approximating the likelihood function
The first election poll is in! \(X\) = 6 of 10 polled voters plan to vote for you. You can use these data to build insight into your underlying support \(p\). To this end, you will use the likelihood_sim data frame (in your workspace). This contains the values of \(X\) (poll_result) simulated from each of 1,000 possible values of \(p\) between 0 to 1 (p_grid).

Bayesian Modeling with RJAGS
Egzersiz talimatları
The ggplot() here constructs the distribution of \(p\) from which each possible outcome of \(X\) was generated. Modify this code, supplying a fill condition in order to highlight the distribution which corresponds to your observed poll_result, \(X=6\). This provides insight into which values of \(p\) are the most compatible with your observed poll data!
Note: do not wrap this condition in parentheses ().
