Thursday HW:

Tonight please complete the following in your textbook--this gives us some practice with finding the expected value (mean) and standard deviation when combining random variables.

Page 383: 25, 27ab, 31bc, 33

• Question #25 gives us some practice with the arithmetic of shifting/rescaling (a-d) and then combining random variables (part e).....
• Questions 27ab and 31bc are based on the ideas we discussed today with the dogs and cats...
• Question 33
• Start with 33d and e
• 33d asks us to find the mean and standard deviation of the total amount of cereal in the two bowls, which is based on our learning today (cats and dogs)
• 33e then challenges us to use this new mean and standard deviation to find a probability with a Normal model--you got this!
• Then go to 33ab...
• 33ab are again referring to combining random variables--back to cats and dogs....
• 33c is definitely the hardest homework question....we're using the Normal model again....good luck!

Tomorrow in class we'll discuss #33 and then look at some more examples with combining random variables (and the Normal model)! Then we'll do some studying this weekend and some classwork/practice on Monday! See you there!

Here'sthe outline of our course through midterm exams:
