Question

which is the joint relative frequency for mall visitors who like seafood and meat?

\\( \frac { 5 } { 72 } \\)

\\( \frac { 16 } { 72 } \\)

\\( \frac { 20 } { 72 } \\)

\\( \frac { 31 } { 72 } \\)

Explanation:

Step1: Recall joint relative frequency formula

Joint relative frequency = \(\frac{\text{Frequency of the joint category}}{\text{Total number of observations}}\)

Step2: Identify values from the table

The frequency of mall visitors who like seafood and meat is \(16\), and the total number of mall visitors is \(72\)

Step3: Calculate joint relative frequency

Joint relative frequency = \(\frac{16}{72}\)

Answer:

\(\frac{16}{72}\)
