The histogram represents data from a total of 27 students.
The histogram mentioned in the question shows the pulse-rate data of students and divides them into different ranges.
To find the total number of students represented in the histogram, we add up the number of students in each pulse rate range:
3 students with a pulse rate in the range of <51 (beats/min)
4 students with a pulse rate in the range of 51-60 (beats/min)
6 students with a pulse rate in the range of 61-70 (beats/min)
7 students with a pulse rate in the range of 71-80 (beats/min)
4 students with a pulse rate in the range of 81-90 (beats/min)
3 students with a pulse rate in the range of >90 (beats/min)
Adding these numbers together:
3 + 4 + 6 + 7 + 4 + 3 = 27
Therefore, the total number of students represented in the histogram is 27.
The probable question may be:
Pulse-rate data were collected from some students during their lunch time for the lab activity, Making Connections. The data are represented in the histogram below.
The histogram includes data from a total of how many Student Pulse-Rate Data students?
3 students with a pulse rate in the range of <51 (beats/min)
4 students with a pulse rate in the range of 51-60 (beats/min)
6 students with a pulse rate in the range of 61-70 (beats/min)
7 students with a pulse rate in the range of 71-80 (beats/min)
4 students with a pulse rate in the range of 81-90 (beats/min)
3 students with a pulse rate in the range of >90 (beats/min)
