- Lab3: Turn in “Homework” problems as an RMarkdown document (submit both the .Rmd source and the output “printed” to a .pdf (might need to Knit to HTML first, then open that in a browser and “print” from there (SLOs: C5, D1, D2, H1, H2, H4, H5)

- Quiz 3: SLOs C5, D1, D2

- Practice Problems (do but don’t need to turn in — solutions are in the textbook to check on your own): 3.25, 3.45-3.55 (odd)
- HW4: 3.2, 3.4 and 3.22 (E1), 3.12 and 3.14 and 3.40 (E3 and E4) 3.64, 3.68(b,c,d) and 3.74 (F1), 3.86 (F2)
- Lab4: Turn in “Homework” problems as an RMarkdown document (submit both the .Rmd source and the output “printed” to a .pdf (might need to Knit to HTML first, then open that in a browser and “print” from there (SLOs: Es and Fs TBD, H1-H5)

- HW5: 3.104 (practice only), 4.10, 4.18, 4.28 (E1 and G1)
- No lab this week

- Quiz 5: SLOs E1, E3-E5, F1

- HW6: 4.130 (E1, G1), B.36 (from Unit B review exercises) (G3, G4), 4.104 (G1, G4), 4.128 (G3), 4.144 (G4, G5)

- Project Proposal (description)

- HW7: 4.176 (G1-G4), 4.134-4.142 (even numbers; G5,G6)

- Quiz 6: SLOs G1-G6

- Lab 5: Turn in “Homework” problems in RMarkdown form (SLOs: H1-H5, I1, I2, I4)
- A Note on “I” SLOs: Please note that the I and J SLOs are treated differently than the A-G SLOs. Their objective is to get you to be comfortable taking a dataset and a question and doing all phases of analysis, from importing the data, visualizing it, estimating parameters, carrying out tests, and interpreting results in context. The associated problems are thus more open-ended than most we have had. In addition, since these objectives do not lend themselves to quizzes, the grade for them is based
*primarily*on homework.

- Lab 6 (SLOs: E6, E10, F1, G1, G4, H1-H5, I2, I3)

- HW8: 6.58 (J1), 6.126 (J3), C.62 (J2),
~~6.224 (J4)~~. Each of these problems asks you to do a hypothesis test using analytic approximations. In addition to the hypothesis test, report and interpret a confidence interval for the parameter(s) of interest. Before carrying out inference, assess whether the conditions for analytic inference are satisfied (but proceed even if not, for the sake of practice). Where applicable, produce plots of the data, and as always, be sure to interpret all results in context.

- Quiz 7: SLOs E5-E10

- Project Pilot Analysis (K1-K4, L1-L4, M1-M2, M5, N1-N2, N4, N6, O1-O2, O5)

- HW9: 6.252 (SLOs E6, E7, J5), 6.224 (J4). The same instructions apply here as for HW8.

- Quiz 8: SLOs D2, E2, E6-E8

- Regression Mini-Project (SLOs: D1-D2, E2, E7, E8, F1, G1, G4, H1-H5,J6)
- Note that the D-G SLOs on this project count with “in class” items

- HW10: Ch 7.30 (J7), 7.48 (J8)

- HW11 (not graded; practice for SLO J9)
- 8.17: Using the scenario described, state hypotheses, evaluate conditions for the F-test, do the test, and interpret the result. If the result is significant, compute confidence intervals for each individual mean compute intervals and do tests for each pairwise difference, using the pooled within-groups variance, interpreting each one.
- 8.38 (include all components of the test)

- Exam 3: required SLO: J9; optional SLOs: various D-G (you will get to pick and choose problems to do, based on the SLOs you need). Unlike on previous exams, you may use the computer on this exam, which will be helpful in particular for the J SLOs.
