Math 151 , Fall 2005, Day 11 Mon. Sept. 19 Hit reload...

--Exam 1  Friday Sept 23, Day 13, in class, closed book.   Bring a simple calculator. I will give you copies of the Normal table.  You may stay late into the lunch hour if you like. If you will need extra time, and can't stay into the lunch hour, make arrangements with me by next Wednesday, please.
Covers Part I:through p.112  but NOT???Yes or no?: "backward" normal problems with raw data like p.90..Percentiles II, p. 92-3 questions 2,3.  You will need to read SPSS output, but not tell how to produce any. You will need to calculate "by hand" a standard deviation for four numbers. (As well as medians, quartiles, etc.)   Problems like HW + some true-false or multiple choice types.
 Sample exam  handed out today; solutions outside my door, on reserve soon.
Day 10(Fri. Feb. 18): Reading: Finish D&V Ch6 pp. 86-98.  (Questions 2&3 p.92-3 are optional. Normal Prob. Plots p. 94-95 is  Optional, but don't miss What Can Go Wrong, p95 bottom).  AS Ch. 6, in order. Note 6-4 ¶1, Normal table does UPPER tail.  Almost all normal tables do LOWER tail.
Then: Quick Review p.103.  Ahead, D&V Ch7 Scatterplots, first thru 117 (AS7-1&2), then Correlation, the rest. (AS7-3&4)
Technology:http://www.whfreeman.com/scc/ , Statistical Applets, Normal Density.  Uncheck the 2-tail box for most uses.  OR ActivStats Normal Density Tool : for best setup Use AS30-2 "Normal distribution based Confidence Intervals tool" CAUTION: Don't hit the Enter key! It closes the tool-box!
Hand in (All D&V)
Raw data problems.   "Backward" parts  are marked with *- do them with table Z.
Make a sketch, label the x and z-scales on the horizontal axis, roughly mark the area you're interested in, compute.
