In all, 25% said that they were satisfied. The dotplot shows the proportion who said they were satisfied in each of 500 random samples of size 1025 from a population where 25% are satisfied. 우 0.2 il 0.21 0.22 0.23 0.24 0.25 0.26 0.27 0.28 0.29 Simulated sample proportion who said satisfied Distribution of simulated proportion # samples 500 mean 0.25 SD 0.014 (a) Use the results of the simulation to approximate the margin of error for the estimate of the proportion of undergrads at the large university who would go to the professor. (b) Interpret the margin of error.
