• Assigned Nov 25 and due Tuesday Dec 2:   10.74, 10.78, 10.92,  and the Case Study about Working Four days a Week. (don't forget the test on Thursday Dec 4.)

Just in case you wondered.  The exact answer for problem number 2 on the test is:
62854296814311299839689500342603597497945305 / 4016396694952252076402944892831460158221423568

• Assigned Nov18 and due Nov 25:  9.48, 9.50, 9.52, 9.53, 9.56, 9.62, 9.65, 9.69 and the Aspirin a Day Case Study.  Hint:  for problem 9.52 read section 9.6 (I didn't talk about this section in class and am not planning to)  it uses the same principles as we have been studying only deals with proportions.

• Assigned Nov 4 and due Nov 13:  8.70, 8.73, 8.74, 8.78, 8.88, 8.98, 8.99  and the Case Study about Polls.

• In Class Activity on Sampling Distrbutions Data  (Not to be handed in)

• Assigned Oct 28 and due Nov 6 (sorry for the typo before of Nov 3):  1.  7.24, 7.26, 7.58, 7.68.  2.  The Monte Carlo Case Study will be Extra Credit.  3.  From the class height data that we collected at the beginning of the semester, make a 90% box plot of that data and find whether the height of 71 inches is likely or unlikely. Find whether a height of 54 inches is likely or unlikely.  Find whether a height of 75 inches is likely or unlikely.  4.  Gorbatch seal rookery, a breeding ground on St. Paul Island in Alaska, wanted to estimate the number of fur seal pups in the rookery.  In early August 1961, wildlife workers captured and marked 4965 pups by shaving some of the black hair from the tops of their heads.  they then released the pups and allowed them to mix with the others.  In late August, when the workers captured a sample of 900 pups, 218 of them had marks.  Give a 95% confidence interval in percents for the true percentage of marked pups.  Give a confidence interval in actual numbers for the total number of seal pups.

• Assigned Oct 7 and due Oct 16:  1.  6.60, 6.64, 6.68, 6.72, 6.76  (These are primarily paper and pencil problems using the Normal Distribution Table on the inside cover of your book.  Although you can use Minitab if you wish.  However on the test you will be given a chart to use not a computer!!)  2.  Long and Short of It Case Study

• Assigned Oct 2 and due Oct 14:  1.  5.70 through 5.73    2.  Reactor Case Study

• Assigned Sept 23 and due Oct 2:  1.  4.118 not using Minitab  2.  4.78 and 4.93 using Minitab  3.  Case Study:  Probability and Decision Making in the Congo.  Add to the Congo problem the following question.  Find the probability that three or fewer fail to make a successful jump. (Neither part of the Congo problem is a Minitab problem)  Note:  To have Minitab draw the probability histograms follow the instructions on page 169 and 170.  You will have to adjust the line size so that the bars are touching.  I found that 85 worked well at least on the screen.  Printing may be a little different.

• Assigned Sept 4 and due Sept 16:  1.  problems 3.19 and 3.20.  2.  Clean Dishes Case Study.  Note:  When you try to do the pie charts, you can only do two on one page not three.  Also to keep from getting four equal sections each time, choose CHART TABLE under OPTIONS.  Also be sure that you have a "category"  for each "frequency" even if it is the same category.  To get side by side bar charts follow the instructions on page 109-110.  For the example given the data should look like this (They neglected to show you how to set up the table):

Status	Frequency	College
Freshman	5	UCR
Sophomore	23	UCR
Junior	32	UCR
Senior	35	UCR
Grad Student	10	UCR
Freshman	10	UCB
Sophomore	35	UCB
Junior	24	UCB
Senior	25	UCB
Grad Student	6	UCB

• Assigned Sept 4 and due Sept 16:  The Summation Project.  It is available in two versions pdf  (the better one) and html (if your computer can't handle pdf)

• Assigned Sept 2 and due Sept 9:  1.  problem 2.61 from the book  2.  Find the mean, median and mode and population standard deviation for the class heights.  3.  Boys of Summer Case Study

• Assigned Aug 26 and due Sept 9:  Using Minitab:  1.  Pie Chart of class standing (Fr., Soph., Jr., Sr.)  2.  Histogram of class heights.  3.  In your book:  1.46, 1.47,  Blood Pressure Case Study.  Note:  Minitab will select random samples for you--you don't need to select them yourself.  Under CALC choose "Random Data". Also, to put two graphs on one chart as in time series, choose "Multiple Graphs" and then "Overlay".  To change from a frequency histogram to a relative frequency histogram, click on OPTIONS in the dialog box and choose "Percent".
