See how close this theoretical distribution is for the middle five columns of the plinko game. These five columns run 2.5 up and down from the theoretical mean (13). Since the theoretical standard deviation is 2.55, these five bins encompass just about ±1 standard deviation. Looking at the scale on the left side, estimate the number of balls in each of the five central columns and enter your estimates in the table below. Add these five values and enter them in the Total column. How closely does this total agree with the theoretical percentage of balls that you would expect to land in this area (±1 standard deviation from the mean)?
