Weekend HW!

If you did not complete last night's homework (complete the 2015 FR then score it using the rubric) you can do so this weekend for full credit. Read the blog post below.

This weekend please complete the following in your textbook (some simulations practice!)

Page 266: 9bc, 13, 23, 25

• For 9b, write a procedure! 
• 9c asks you do describe/define the response variable--you likely answered this within your procedure, so you don't necessarily have to re-write this again
• For 13, 23, and 25...
• Write a procedure
• Simulate--conduct 5 trials for each simulation!
• Write a conclusion
• Use the random number tables below for each question!
• For 13:
• The question asks, "what are the chances you get them all right?" So, you final answer for this simulation will not be an average, it will be a probability ("the chances")! Run your 5 trials and find the probability you get all six questions right (how many times did you get all 6 right out of the 5 trials?)

• For 23:
• For this question, we have 100 cards labeled with different with different "prizes." Remember, two digit #'s from 00-99 give us 100 different #'s, so we should use 2 digits here. In this case, when we give one of the $50 prizes away (for example), we cannot give that prize again--so for this simulation we'll have to ignore repeats! This is the first time we've seen this in a procedure!

• For 25
• Use the example from class to help with this simulation! We have a different "stopping rule," but it's a similar process.

How about some extra credit?

• The video linked below describes the Monty Hall Problem--check it out!
• Monty Hall Problem!
• You can also check out this link to ready more about this famous Statistics problem...
• 2 Goats, 1 Car
• Here's the extra credit assignment:
• In your own words, describe (in complete sentences) the context of this problem.
• Then, in your own words, describe the "solution" to this problem.
• In other words, write a few sentences summarizing what the Monty Hall problem is all about! Be detailed! 

And lastly, if you're feeling super ambitious, here's Monday night's homework--more simulations! You can use the same random number tables (above) for these if you like:

Page 267: 19, 21

• For each, write a procedure, simulate (5 trials), then write a conclusion!
• These are a bit trickier than the weekend hw!
• For 19 we will have more than the 5 steps we saw in class--because the probability of passing the driving test changes after the first attempt, we will have two "breakdowns" (step 2); we will have to have a breakdown for numbers that represent passing for the first test, and this will then change for the following (subsequent) tests!
