upper limit      


Give a brief explanation of the meaning of your answer in the context of this problem.

We are 1% confident that the true proportion of Colorado physicians providing at least some charity care falls within this interval.We are 1% confident that the true proportion of Colorado physicians providing at least some charity care falls above this interval.    We are 99% confident that the true proportion of Colorado physicians providing at least some charity care falls outside this interval.We are 99% confident that the true proportion of Colorado physicians providing at least some charity care falls within this interval.


(c) Is the normal approximation to the binomial justified in this problem? Explain.

No; np < 5 and nq > 5.Yes; np > 5 and nq > 5.    No; np > 5 and nq < 5.Yes; np < 5 and nq < 5.
