Answer to Question 1

TRUE

Answer to Question 2

Cumulative relative frequency distributions not only tell us the proportions or percentages in the sample or population less than a certain value, but we can take the differences and find the actual cumulative relative frequencies in each class from this distribution. Moreover, as long as we know the total sample or population size, you can get the actual frequencies as well.
