Date       Assignment


09/01/00             Using the Test 2 data, compute the mean, make a stem and leaf diagram,
                           compute a 5 number summary, and on the same axis, sketch the box plots
                           for Test 1 and Test 2. (1)

09/06/00             P. 87:  40, 41.  Compute 2 standard deviation interval for test 2 data and find
                           percentage of data in the interval. (2)
09/08/00             P.306:  28, 31a, 32c.  Estimate the mean test score for test 1 and test 2 with
                           85% confidence intervals

09/11/00             P353:  8c, 9 (use alpha = 0.05), 10,11   P394: 9, 12
09/13/00             P344: 10, 14a and analysis of young and old clocks (oldClocks.doc on g:)
09/15/00             P359: 17,18    P 403: 27,28

09/20/00             compute p-value for hypothesis tests in problems 8, 9b, 10 and 12 on P. 353
                           P430:  62a(do as 2-tailed test) and 66
09/22/00             P.523:   6,7,9 - plot scatterplot, find least squares line, plot line in scatterplot

09/25/00             P523:  6,7,9 - compute SSyy, SSE and MSE
09/27/00             P523:  6,7,9 - test hypothesis that slope is not 0

10/02/00             Test 1
10/04/00             P523:  6,7,9 - Compute R-squared.  Use all 32 observations of age and clock price data
                           Find least squares line, test hypothesis on slope, compute R-squared.
10/06/00             Practice using SPSS.  ( Use age and saleprice data)
