You wish to determine if the amount of time people spent outdoors has decreased since many of the COVID restrictions have been removed (during COVID people spent more ti e outside because indoor activities had been curtailed). A very large scale study in 2021 during the COVID lockdown found that Canadian adults spent an average of 2.15 hours outside (St Dev = 0.96) You randomly select 20 members of your rowing club and find that they spend 2.87 hours outside (St Dev = 1.12) What is the Dependent Variable? What is the Independent Variable? Is this a study or an experiment? (why?)What is the appropriate test to use? WHY?

What is the biggest problem with this research design and how would you fix it?
