Question

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 following grouped frequency distribution. what is the class width? the class width is (type a whole number)

Explanation:

Step1: Subtract the lower limit of a class from the upper limit

Take the first class \(35 - 39\). The upper limit is \(39\) and the lower limit is \(35\).

$$39-35$$

Step2: Calculate the result

$$39 - 35=4$$

Answer:

\(5\)

(Note: There was a miscalculation in the initial step - by using the next class's lower limit minus the previous class's upper limit. For example, \(40-39 = 1\) (this gives the gap between classes). Then using the formula \( \text{Class Width}=\text{Upper limit}-\text{Lower limit}+1\). For the class \(35 - 39\), \(\text{Class Width}=39 - 35+1=5\))
