The frequency table that shows the relative frequency of people older than 40 and don't visit the dentist is:
D. Visit Dentist Yearly Don’t Visit Dentist Yearly
Below 40 0.27 0.73
Above 40 0.57 0.43
<h3>What is the relative frequency required?</h3>
The relative frequency of those older than 40 and don't go annually to a dentist can be found as:
= Number of over 40 who don't go to dentist / Total of those over 40 surveyed
Solving gives:
= 13 / (17 + 13)
= 13 / 30
= 0.43
