Zoey was playing with a spinner that has 4 equal areas numbered 1 2 3 and 4 Zoey spun the spinner 50 times and 20 of the 50 spins came up as a 4 She wanted to see how likely a result of 20 fours in 50 spins would be with a fair spinner so Zoey used a computer simulation to see the proportion of fours in 50 spins repeated 200 times assuming a probability of of spinning a 4 Create a 95 confidence interval based on the data from the simulation to the nearest hundredth and state whether the observed proportion of fours is within the margin of error of the simulation results Mean 0 251 SD 0 061 booo 0 04 0 08 0 12 0 16 888 0 2 0 24 0 28 0 32 0 36 0 4 0 44 0 48 Proportion of Fours cxxxxx Note don t use percents for the interval or sample proportion The confidence interval based on the simulation is observed proportion of fours of simulation is so the of the fair spinner s
