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.
To find the joint relative frequency of elementary age students who prefer winter, we first need to determine how many elementary age students prefer winter.
From the table, we can see that 84 elementary age students prefer spring, 36 prefer summer, and 120 prefer winter. Therefore, the joint relative frequency of elementary age students who prefer winter is:
120 / 251 ≈ 0.478
Rounded to the nearest whole number, the joint relative frequency is 48%.
