Question

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.

Answer 1

Answer:

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.

Answer 2

The first answer is observational study.
the second answer is published data
third answer is simulation<span />
