Elizabeth was playing with a spinner that has 3 equal areas numbered 1 2 and 3 Elizabeth spun the spinner 100 times and 23 of the 100 spins came up as a 3 She wanted to see how likely a result of 23 threes in 100 spins would be with a fair spinner so Elizabeth used a computer simulation to see the proportion of threes in 100 spins repeated 100 times assuming a probability of of spinning a 3 Create a 95 confidence interval based on the data from the simulation to the nearest hundredth and state whether the observed proportion of threes is within the margin of error of the simulation results 1 Mean 0 331 SD 0 048 0 2 0 25 ooooo oooooo 0 3 0 35 Proportion of Threes 0 4 0 45 0 5 Note don t use percents for the interval or sample proportion The confidence interval based on the simulation is observed proportion of threes of is spinner s simulation so the of the fair
