(iii) The suggested class interval based on number of observations given the data ranges from 100 to 200 with 50 observations is 20
A) (i), (ii) and (iii) are all correct statements.
B) (i), (ii) and (iii) are all false statements.

(i) A frequency distribution is indeed a table showing how observations are distributed across several classes. (ii) Classes in a frequency table are constructed to be mutually exclusive, meaning each data point can fit into only one category.
