(a) Do you believe that the MCMC sample size is adequate? Why or why not? If you feel it is inadequate, than rerun JAGS with a larger MCMC sample size. Is the length of the burn-in periods adequate?...

 (b) Construct time series and ACF plots of the parameters theta, sigma, ypred[1], and ypred[2]. What do the plots tell us about MCMC mixing and convergence?

 (c) Find a 90 % posterior interval for the next observation after the observed data.
