The percent of kindergartners surveyed who can ride a bike is less than the percent of first graders surveyed who can ride a bike.
Step-by-step explanation:
Given: The table shows the relative frequencies of the rows for the two-way table representing this situation.
The relative frequency for kindergartners surveyed who can ride a bike=0.32
Then, the percent of kindergartners surveyed who can ride a bike=![0.32\times100=32\%](/tpl/images/0155/7184/20425.png)
The relative frequency for First graders surveyed who can ride a bike=0.56
Then, the percent of First graders surveyed who can ride a bike=![0.56\times100=56\%](/tpl/images/0155/7184/a0674.png)
Clearly, 32 is less than 56.
Therefore, the percent of kindergartners surveyed who can ride a bike is less than the percent of first graders surveyed who can ride a bike.
