Hi ,
My second midterm exam prep seminar is coming on Saturday, Mar. 5. Go to www.grantstutoring.com for more info and to register.
Simply go to www.grantstutoring.com and click the Facebook and/or Twitter icons.
You are receing this email because you indicated when you signed up for Grant's Updates that you are taking Stat 1000 this term. If in fact, you do not want to receive tips for Stat 1000, please reply to this email and let me know.
If you ever want to look back over a previous tip I have sent, do note that all my tips can be found in my archive. Click this link to go straight to my archive:
Throughout the term I will send you all sorts of tips to help you study and learn the course. You probably already have done so, but, if not, I strongly recommend you purchase my Basic Stats 1 Study Book. You will find it a great resource to learn the course. I pride myself in explaining things in clear, everyday language. I also provided numerous examples of all the key concepts with step-by-step solutions. You can order my book at UMSU Digital Copy Centre at University Centre at UM campus. They make the book to order so please allow at least one business day. The book is split into two volumes and each volume costs $45 + tax.
Tips for Web Assign HW 06
When working with Web Assign, always enter the answer to one specific box and then click "Submit Answer" to confirm that is correct before you move on to another box. Do not enter several answers all at once in several boxes before you click "Submit Answer". You risk being marked wrong due to some typo or something.
For some strange reason, JMP 8 occasionally computes wrong answers even if you have copied and pasted your data correctly. I suggest that, if it is feasible, type the given data into your calculator (in Stat mode as shown in Appendix D of my book), and have your calculator compute the sample mean. Compare that answer with JMP's answer for the sample mean. If they are the same, everything is fine. If they are not the same, close JMP 8 and restart it, recopy and paste the data, and check again. Sometimes you have to do this 2 or 3 times before JMP finally works. If it is not feasible to use your calculator to compute the sample mean, have JMP do the question 2 or 3 times, being sure to restart JMP and recopy the data each time, and confirm that JMP gives you the same answer each time before risking entering the results into Web Assign.
For the JMP 8 part of the assignment, here are some tips:
Once you have installed JMP 8 and opened it, you are shown a menu with various buttons to click. You will almost always click "New Data Table" to enter new data. In the rare event they have given you a JMP file with the data already entered in it, you will simply open that file which would probably already open JMP for you. If you happen to enter data in yourself and save the file (a good idea), you can select "Open Data Table" to open up the saved file.
To copy and paste data into JMP: First, of course, select and copy the given data set. Now, open JMP and click "New Data Table". In the toolbar at top select "Edit" then "Paste with Column Names". That pastes all the data in and names the column appropriately.
Note, you must save your document as a PDF file to upload it into Web Assign (no other format will be accepted). If you don't know how to do this for the software you are using try the help files or Google "save as pdf file" for some helpful steps or programs that enable you to save documents that way for free. MS Word 2007 is capable of saving as pdf. If you are using a different program and do not have a "save as pdf" option, download the "pdf writer" they give you in Web Assign or Stats Portal. If you are unable to "save as pdf", try selecting "print" as though you were going to print your file, then select your "pdf printer" rather than your physical printer in the print options. That will then save your file in pdf form.
If you are taking the course by distance/online (Section D01) click here to see your tips for HW 06.
No tips are ready at this time. I will send you tips for HW 06 later.
Continue to study Lesson 4 in my book, if you have it, to prepare for this assignment.
Thankfully, there is no JMP needed for this stuff.
Question 4
When they ask you what the number in bold is, all they want you to say is that it is either a parameter or a statistic. I define what those two things are at the start of Lesson 2 in my study book.
