Two's Day HW!

Tonight please complete the homework worksheet provided in class--labeled as "Summer Academy: Day 3 HW" (obviously we didn't get to it in the summer).

• Don't have a copy or you were out? Here's a link!
• Two Way Table Probability HW!
• We did not get to answer a question like C in class, but think about it...
• Compare your answers to a and b
• A gives us the probability any random passenger survived
• B gives the probability that someone survived if we knew they were in first class
• Based on those probabilities, does it seem like "class" impacts your chance for survival? How/why?
• For the last MC:
• This is arguably the most important question on the paper--so take your time with it!
• DON'T JUST READ THE ANSWER CHOICES AND PICK ONE--it take more than that
• Do the math and write down fractions/probabilities
• For example, for option A: "person who completed more advanced studies" = 40/100, and "being a person who did not complete more advanced studies" = 60/100, so this is false! 
• We'll take a look at the answers tomorrow in class, so no scoring tonight. 

Tomorrow we'll wrap up our discussions of two way tables, answer homework questions, and then start writing about histograms/stemplots/dotplots etc. See you there!
