To find the joint relative frequency of elementary age students who prefer winter, we need to look at the data for elementary age students who prefer winter. From the table, we see that 84 elementary age students prefer winter.
The total number of students surveyed is 251, so the relative frequency of elementary age students who prefer winter is:
(84/251) * 100 = 33%
Rounding to the nearest whole number, the joint relative frequency of elementary age students who prefer winter is 33%.
Elementary Age 84 36 120
Middle School Age 26 105 131
Total 110 141 251
The table shows survey data about which season students prefer. What is the joint relative frequency of elementary age students who prefer winter? Round to the nearest whole number.
