I is true because the weight for actual observations and percentages is same. II is true because the ranges or classes are same. III is false because we mark actual or percentage respectively. |

1) Is true because relative frequency is just another way to express to amount of observations that falls into a class but in % instead of number. Therefore, 2) is true since the horizontal axis mesures the frequency in both situation 3) is false since the vertical axe changes from # / %. |
