Statistics Practice Quiz 1.3 Let's dust off those math skills and recall those lessons we've forgotten........ " Please Excuse My Dear Aunt Sally" P E M D A S This is a phrase you'll need to help remember the proper "order of math operations." The first letter of each word stands for something mathematical. Please write them in to the blocks above. Then use the order of operations to complete the problems below, by directly substituting the numbers for the letters in the problems (when the letters are DIRECTLY NEXT TO ONE ANOTHER simply write them in) if there is an OPERATOR between them then perform that operation. Example: if c=4 and b=8 170.4cb becomes 170.498 a = 6 b = 8 c = 4 d = 3 1. a x 3 + b x 2 - 10 = 2. 16 - c + a = 3. b x c = 4. (-8)(-4)(-d) - 3 = ___ 5. c = _______ 6. .0000ab = 7. Round b.ab to the nearest tenth = (these are not trick multiplication problems, just put in the values for a, b, c, and d 8. Round c.acc to the nearest whole number = 9. Round d.abc to the nearest hundredth = 10. Population data are used to create: 11. Sample data are used to create: 12. Give an example of categorical data: 13.
