QUIZ 1



opens Fri, Sept 2, 11:30am, closes Fri, Sept 9, 5pm
3 chances, 1 hour time limit each, highest score counts
questions will change, sometimes slightly, so READ carefully


material from Review of STA 2023 (which case, Ha, interpreting p-values and
confidence intervals)
NOTE - highest score should be 10 but I messed up one of the questions and it's scoring
it out of 1pt instead of 2pts. So if you get a total score of 9 it means you did everything
correct. This system is NOT very forgiving, so I can't fix this problem while the quiz is
running. Once the quiz closes I will add 1 pt to everyone's score. Sorry about that.
