a. What is the test statistic? b. What is the p-value? (Round your answer to four decimal places.) c. Construct a 95% confidence interval for the true proportion. Sketch the graph of the situation. Label the point estimate and the lower and upper bounds of the confidence interval. (Round your answers to four decimal places.)
