Tuesday HW + Stamps!

1.) Tuesday's HW:

1. Please complete the "Reading Computer Outputs (Stamp)" worksheet provided in class or linked below
• AP Stat: Reading Computer Outputs
2. AND complete the following problem on the back of the worksheet...
• (This is #27d on page 191-192)
• A scatterplot was created to see the association between math and verbal (writing and language) SAT Scores.
• Verbal scores are used as the explanatory variable and math scores are used as the response
• The verbal scores averaged 596.3 with a standard deviation of 99.5, and the math scores averaged 612.2 with a standard deviation of 96.1.
• The correlation for these variables was r = 0.685.
• Write the equation of the regression line.
3. ALWAYS CHECK YOUR ANSWERS!
• Reading CPU Outputs KEY
• Answer to #27 (above):
• predicted math score = 217.7 + 0.662(verbal score)

2.) STAMPS ARE DUE TOMORROW! 

• All stamps are due Wednesday! These count as a classwork grade! And it's a pretty big classwork grade (largest of the quarter) since it's for all of our warmups combined!
• What do I do?
• Gather all your stamps. You are literally looking for a red stamp, not a paper titled "stamp." 
• Somehow fasten/get all your stamps together
• Clip them all together
• Put them all in an envelope or folder
• Some students cut out the stamps and glue them to a piece of paper or put them in a baggie
• You can do whatever works for you!
• Count all your stamps. Count them again.
• Write the total and your name on the front of your stamp.
• Double check your count.
• I will randomly select 5 names from each class and re-count these peoples' stamps; if your total is incorrect you will be given a 0.
• You must do this outside of class. If you count/gather your stamps in class you will be given a 0.
