Question

According to a recent survey of 1300 people, 64% feel that the president is doing an acceptable job. We are interested in the population proportion of people who feel the president is doing an acceptable job. NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)

According to a recent survey of 1300 people, 64% feel that the president is doing an acceptable job. We are interested in the population proportion of perole who feel the president is doing an acceptable Job NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though) Part() Part Which distribution should you ine for this problem? (Round your answers to four decimal places) P- Explain your choice The Students distribution should be used because we do not know the standard deviation O The binomial dabribution should be used because the two outcomes are the president is doing a good job and the president is not doing a good job The standard normal distribution should be used because neg a 10, which imples a large sample O The standard normal distribution should be used because we are interested in proportions and the sample size is large Part Construct a 90% confidence interval for the population proportion of people who Stale the confidence interval. Round your answers to four decimal places) 0) Sketch the graph [[[[810] a the president is doing an acceptable job C.L. = 81 11
