Use the drop-down menus to identify the method used to collect data for each scenario. while standing in front of the school, jace recorded the number of students who walked, rode their bikes, took the bus, and were driven there. noah researched statistics online about the percentage of babies born with brown eyes. lara knew that she had a 25% chance of winning a contest, so she flipped two coins repeatedly to determine how many times two heads occurred.

Step-by-step explanation:

I.  While standing in front of the school, Jace recorded the number of students who walked, rode their bikes, took the bus, and were driven there

This is an observational study because this is taken as observing all possible ways.

2. Noah researched statistics online about the percentage of babies born with brown eyes.

This is not directly done but from primary data already collected already.  Hence this is secondary data taken from published data.

3. Lara knew that she had a 25% chance of winning a contest, so she flipped two coins repeatedly to determine how many times two heads occurred.

This is already having an idea of 25% she wants to check it.  This is simulation.

This is referred to as an observational study because all the possible ways and methods were explored to arrive at an accurate data.

Noah made his research to find out the statistics involving the percentage of babies born with brown eyes. This is referred to as a secondary data as it wasn't done directly by him.

Lara knew that she had a 25% chance of winning a contest, so she flipped two coins repeatedly to determine how many times two heads occurred is an example of Simulation as she wanted to check if se will arrive at the same result.
