Student Name: Grade Computation RES342_S3.

The Web-based company Oh Baby! Gifts has a goal of processing 95 percent of its orders on the same day they are received. If 484 out of the next 500 orders are processed on the same day, would this demonstrate that they are exceeding their goal, using α = 0.01?

Instead, you must save the file to your hard disk. Then open the file from your hard disk. Do your work, save the file, and exit from Excel. Then send the file back to me as an attachment to an OLS message. Any other approach is almost guaranteed to corrupt the file and make it unusable. Look below and find the row of tabs. One of them is a "Tip Sheet" that gives some of the answers you need to compute, so you'll know when you succeed in computing them. There is another tab for each problem you are to work. The Output sheet is provided in case you use MegaStat – it will put its output there. If you use MegaStat, then copy the pertinent cells from the Output sheet to each problem sheet. Please delete this warning box so you can see the Grade Computation Worksheet. Simply click on it and press the Delete key.

Tip Sheet When you’re working the problems in this course, it’s a big help if you know what the answers are. Exercise S3-1 a) b) c) Use the t statistic. Explain why you must do this. Give the formula for t. d) Critical t value is 2.12 e) Actual t value is 5.18 f) p-value is 0.0000035182 (or 3.51817E-06) Exercise S3-2 a) b) c) Use the Z statistic. Explain why you can do this. d) Critical Z value is 1.645 e) Actual Z value is 2.263 f) p-value is 0.012. Don’t forget to state the interpretation of this number. Exercise S3-3 a) b) c) Use the Z statistic. Explain why you can do this. d) Critical Z value is 2.326 e) Actual Z value is 1.847 Exercise S3-4 a) b) c) Use the t statistic. Explain why you must do this. d) Critical t value is 1.9740 e) Actual t value is 1.9232 Don’t just copy any of the information from this tip sheet to your homework. This is provided solely as a way for you to know whether you’re on the right track. If your procedure results in these numbers, chances are you’re doing everything correctly. If not, you’ve got something wrong. You will get no credit for writing down these numbers, unless you also provide calculations that result in these numbers.
