A group of kindergartners and first graders were asked whether or not they can ride a bike. This table shows the relative frequencies of the rows for the two-way table representing this situation. Select from the drop-down menus to complete the statement. The percent of kindergartners surveyed who can ride a bike is (choose-greater than ,less than, equal to) the percent of first graders surveyed who can ride a bike.
   Can ride a bike Cannot ride a bike
Kindergartners.   0.32. 0.68
First graders.    0.56.   0.44

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.

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=[tex]0.32\times100=32\%[/tex]

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=[tex]0.56\times100=56\%[/tex]

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.
