The percentage of kindergartners who can ride a bike is less than because 0.32 is less than 0.68. 32 is less than 68. (READ YOUR QUESTIONS BEFORE POSTING.)

Answer: The percent of kindergartners surveyed who can ride a bike is less than the percent of first graders surveyed who can ride a bike.

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*100=32\%

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*100=56\%

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.
