Answer 1

Explanation:

30-35////////1035-40////////1040-45////545-50///////////1350-55////455-60—060-65////465-70//2Suggestions on constructing a frequency distribution(1)Equal-size class intervals should be used:Whenever possible, the class intervals used in afrequency distribution should be equal. Unequal class intervals present problems when thedistribution is portrayed graphically. Unequal class intervals, however, may be necessary in certainsituations in order to avoid a large number of empty or almost empty classes.
