Question

social interactions
a professor had students keep track of their social interactions
for a week. the number of social interactions over the week is
shown in the frequency table below.
using the table answer the following:
a. how many students participated in the study?
b. what is the class width?
c. what class has the highest frequency?

Explanation:

Step1: Find total number of students (A)

Sum all frequencies: \(14 + 16+11 + 20+16+12+4+6+0+4\)

$$
LATEXBLOCK0
$$

Step2: Calculate class width (B)

Take two consecutive lower - class limits (e.g., \(30 - 25=5\))

Step3: Identify class with highest frequency (C)

Compare frequencies: \(14,16,11,20,16,12,4,6,0,4\). The highest frequency is \(20\) which corresponds to the class \(40 - 44\)

Answer:

A. \(103\)
B. \(5\)
C. \(40 - 44\)
