The following are the Pulse Rates of the 12 students in a Math Class 76 60 59 60

81 72 91 80

80 68 73 77

If we create Classes for a relative frequency distribution.

For the Class 50-59 , find the frequency

1

Step-by-step explanation:

Given the pulse rate for 12 students :

76 60 59 60 81 72 91 80 80 68 73 77

Creating class intervals ::

Width = 10

59, 60, 60, 68, 72, 73, 76, 77, 80, 80, 81, 91

Interval Frequency

50 - 59 1

60 - 69 3

70 - 79 4

80 - 89 3

90 - 99 1

Frequebcy if the 50 - 59 class interval is 1

11

step-by-step explanation:

32.50-7.50=25

225/25=11
