Question

a group of tourists were surveyed about the number of countries they have visited. their responses are summarized in the relative frequency table below. what is the cumulative relative frequency of tourists that have visited 12 or fewer countries? |countries visited|relative frequency| |---|---| |2|0.10| |10|0.25| |12|0.20| |16|0.20| |20 or more|0.25|

Explanation:

Step1: Identify relevant relative frequencies

We need the relative frequencies for countries visited 2, 10, and 12 (since we want 12 or fewer). Their relative frequencies are 0.10, 0.25, and 0.20 respectively.

Step2: Sum the relative frequencies

To find the cumulative relative frequency, we add these values together: \(0.10 + 0.25 + 0.20\)

Step3: Calculate the sum

\(0.10 + 0.25 = 0.35\), then \(0.35 + 0.20 = 0.55\)

Answer:

0.55
