the accompanying histogram shows the heights of the students in kyras health class. what is the total number of students in the class? 1) 5 2) 15 3) 16 4) 209
Answer
Explanation:
Step1: Identify frequencies per interval
From the histogram, the frequencies for the height - intervals 160 - 169, 170 - 179, 180 - 189, 190 - 199, 200 - 209 are 2, 4, 5, 4, 1 respectively.
Step2: Sum up the frequencies
The total number of students is the sum of these frequencies. So, $2 + 4+5 + 4+1$. $2+4 = 6$, $6 + 5=11$, $11+4 = 15$, $15 + 1=16$.
Answer:
- 16
