Questions+for+Dr+B+and+my+classmates

Study session Monday April 26th 3pm 6th floor Everett Tower, Alavi Commons Room (south end of building).

I have a question about the tree diagram in part one.... Do we have to make two separate tree diagrams and if not how can I do it. I attempted to start out with only two branches but I am now starting to think that there has to be four. Help please!!! I figured it out.... One has to shoot before the other one. Ted will be stage one and Gary will be stage two.

When does everyone want to have a study group with Dr. B on Monday? 9 am: I 9:30: I dont remember the rest of the times... If you do add them please:)

I have a question about the first page Problem B on the project. It says Since Gary is a poorer shot, he shoots first. They alternate shots until one of them wins by hitting the bull's eye. What is the probability that Gary will win the competition? I'm not sure how to go about doing this one. I did Problem A in ProbSims-> Random numbers like we were doing in class today and I was planning on doing the same for this one. However, I'm not really sure how. I started and got through about 20 trials of just going until "Gary made a shot" (1-3 came up) but I started thinking about it and noticed that Ted got plenty of hits before Gary finally did. What should a trial be? Until Gary gets one even though Ted's making shots or everytime Ted makes a shot start over until we get Gary to make a shot before Ted and than have that be one trial. I kind of think the last part... what about you?

Answer: Try thinking about it in the sense that a trial is up to the point when one of the shooters hits the bullseye and wins. this way, you will have an accurate interpretation of the probability of gary winning/ hitting the bullseye before ted.

I have a question about part 1 of project 2. The problem states that the each will shoot at the target one time, but then it says that the only way Ted can win is if he gets more bull's eyes than Gary. Does this mean that they each shoot once, if Gary and Ted both get a bull's eye then Gary wins, and the only way that Ted will win is if Gary does not get a bull's eye and Ted does?

In regards to Writing #2, I am able to find data sets that fit the criteria, but I am having a hard time coming up with a description as to why this is true. Can someone point me in the right direction? Maybe some page numbers in the text where it explains this? Thanks :) This is connected to our discussions about the teacher's salaries (Keats and Longfellow) and the What happens if handout.

survey projects number 72 does not have a college it just says junior twice.... and the students are number wrong so there are only 86 not 87 it jumps from 36 to 38. These are good questions about the data; let me know if your classmates do not respond soon!!! Dr B

Just curious to know if it is possible for a data set to have two modes? also, for the survey information there is one value for the number of classes that is 4 classes plus a lab.... should we count this as 5 classes or four???? (Charlotte) Clue: An answer to the first part of your question is in your text where it first talks about mode. The second part your classmates need to discuss. GOOD question.

On a side note, I was wondering when we were discussing the difference between the problem and the question in class, we were giving examples where the problem was a question and then the question was a more specific question. In my case, I made the problem a statement, is this appropriate or should it be a more broad question? The problem is more of a statement; a problem exists, and we state it. The research question then focuses on the problem statement in a broad sense. Since we will use surveys to address the research question, we will develop questions that focus on more specific things related to the research question. Hope this helps.

​//Feb. 14, 2010 I've just sent a blanket email to our class. I've tried several times to access the information on google.docs but not having any luck. Any assistance would be greatly appreciated. Dawn Cooper//

Dr.B I was wondering if there is a policy for late papers? Yes, it is on the course description handout.
