Question

Based on the frequency distribution above, is 19 a:

Please, anyone, help me and please explain step by step the solution :D

Ages Number of students 15-18 19-22 23-26 27-30 31-34 35-38 4 8 6 3 Based on the frequency distribution above, is 19 a: Class midpoint Class width Class boundary Upper class limit Lower class limit

Answer 1

In given data, the class of ages are 15-18, 19-22, 23-26 ,27-30, 31-34, 35-38.

Where 15,19,23,27,31,35 are lower class limits

18,22,26 etc are upper class limits

The smallest number within the class limit is lower class limit

Hence in class 19-22, 19 is lower class limit.

Hence correct answer is lower class limit.

Answer 2

Ages	Number of students
15-18	2
19-22	4
23-26	8
27-30	9
31-34	6
35-38	3

Based on the frequency distribution above, is 4 a:

• Lower class limit

• Upper class limit

• Class boundary

• Class width

• Class midpoint
