Question

a sample of 246 adults is selected. the adults are classified according to voter registration status (
egistered\ or
ot registered\). they are also classified according to preferred source of current events information (\television\,
ewspapers\,
adio\, or \internet sites\). the results are given in the contingency table below.

among the adults in the sample who are not registered to vote, what is the relative frequency of those who prefer to obtain their information through television?
round your answer to two decimal places.

Explanation:

Step1: Find the number of not - registered adults who prefer television

The number of not - registered adults who prefer television is \(48\).

Step2: Find the total number of not - registered adults

The total number of not - registered adults is \(48 + 39+17 + 34=138\).

Step3: Calculate the relative frequency

The relative frequency formula is \(\text{Relative Frequency}=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). So, the relative frequency \(r=\frac{48}{138}\approx0.35\)

Answer:

\(0.35\)
