Assigned  Due  Assignment 
Mon, Jan 7  Wed, Jan 9  Read section 1.3 on histograms before class on Wednesday. 
Wed, Jan 9  Fri, Jan 11  Read: pp. 210218 (don't get too bogged down with the few terms
we haven't covered yet, such as variance. Variance is nothing but
the square of standard deviation, so it's another measure of spread.) Do: p. 219, #4. 
Fri, Jan 11  Mon, Jan 14  Do: p. 220, #10; p. 219, #2 (in addition to the 90% CI, also find a 99% CI). 
Mon, Jan 14  Wed, Jan 16  Read: pp. 186189 Do: pp. 191192, #8 and #10 
Wed, Jan 16  Fri, Jan 18  Read: pp. 262264 Do: pp. 266267, #8 
Fri, Jan 18  Mon, Jan 21  Read: pp. 267269 Do: p. 269, #2 and #4 
Mon, Jan 21  Wed, Jan 23  Read: pp. 270273, plus read Problem #7, p. 273 Do: p. 273, #2 and #6. Answer each question (a) using previous data and (b) without any prior knowledge. 
Wed, Jan 23  Fri, Jan 25  Read: pp. 227229 and pp. 274275 Do: p. 230, #6. Also, suppose that the study in #6 is conducted and we obtain phat=.538 and n=814. Compute a pvalue for the test and interpret it at level alpha=.05. 
Fri, Jan 25  Mon, Jan 28  Read: pp. 278286. Notice the differences and similarities
between Section 8.5 and Section 8.6. Do: p. 287, #2 and #5. In each, give a 95% confidence interval for the difference between the true proportions. 
Mon, Jan 28  Wed, Jan 30  Read: pp. 4649 (Example 1.5.2 through sample range) Do: Calculate, both by hand and using Minitab, the sample variance and standard deviation for the sample 11, 13, 14, 15, 16, 21. How do the answers change if you add 10 to each number? If you multiply each by 10? Hints: Go to a PC lab somewhere and start Minitab. Type the sample into one column, say C1, with one observation per cell. Then select Basic Statistics...Display Descriptive Statistics from the Stat menu. Enter C1 in the Variables window and click OK. You can copy and paste your results into a word processor or print them out straight from Minitab. Print out your Minitab results, then use the same sheet to answer the questions by hand to save paper. 
Wed, Jan 30  Fri, Feb 1  Read: pp. 220224 and pp. 230235 Do: p. 225, #6. Give a pvalue to answer the last question.

Mon, Feb 4  Wed, Feb 6  Read: pp. 290292, pp. 302305 Do: Minitab assignment 1 
Wed, Feb 6  Fri, Feb 8  Read: pp. 310312. Do: p. 312313, #2 and #6 (the SmithSatterthwaite approximations give df of 123 and 12, respectively) 
Mon, Feb 11  Wed, Feb 13  Read: pp. 8085. Do: p. 8587, #4 and #10. In #4(e), give probabilities for all 16 paths if you can. In #10(c), explain how Mendel's first law is used in the answer. 
Wed, Feb 13  Fri, Feb 15  Read: pp. 8889 and pp. 9094. Do: p. 9495, #4 and #8 (Try to answer #4 with 5 personsbut don't construct a tree) 
Fri, Feb 15  Wed, Feb 20  Read: pp. 9798 and pp. 99100 (notice problem #9 on p. 99) Do: As we discussed in class, there are 52 choose 5 or 2,598,960 different 5card poker hands possible. There are nine categories of hands: Royal flush, straight flush, 4 of a kind, full house, flush, straight, 3 of a kind, 2 pair, and 1 pair (we won't consider the tenth category, which is none of the above). See (for example) http://www.pagat.com/vying/pokerrank.html#standard if you need an explanation of the hands. Your assignment is to demonstrate how to calculate the number of hands in each category. 
Fri, Feb 22  Wed, Feb 27  Read: pp. 111114 and pp. 115118. Do: p. 114115, #2 and #6; p. 119, #4 NOTE: I changed the deadline for this assignment.

Wed, Mar 27  Fri, Mar 29  Read: None Do: p. 339, #3. In addition to the questions asked, use both Levene's test and a residual plot to comment on the appropriateness of the ANOVA assumptions.

Mon, Apr 1  Wed, Apr 3  Read: pp. 398403 (including Estimating an individual response) Do: p. 4067, #4 (a), (c), and (d). 
Wed, Apr 3  Fri, Apr 5  Read: pp. 426430 Do: In the fall semester of 1999, a survey was given to over 200 people taking statistics 200. Assume that the people taking the survey are a representative sample of Penn State students (this is not a reasonable assumption; however, we make it here only for the purpose of this assignment). Download the survey data (save it, then load it into Minitab as a .txt worksheet). Read the survey questions, then answer the following questions by whatever means seem appropriate: Is there a statistically significant relationship between grade point average (question 18) and:
