## Math 11 Homework Assignments, Fall 2017

Math 11 homework assignments will be due approximately weekly. Please work carefully, and show the steps in your calculations, not just the final answer. A selection of problems will be chosen each week to be graded, both for completeness and correctness.

Answers to a few of the assigned problems will be posted in TritonEd, so that you can get some immediate feedback. However, answers will not be provided for all problems. Even-numbered problems are typically similar to the preceding odd-numbered problem, so you could consider working the previous odd-numbered problem first and checking your answer to make sure you are on the right track.

Homework solutions will be posted in TritonEd after the due date. They are for your personal use only. Distributing them to future Math 11 students, or anyone else not currently enrolled in Math 11, or posting them online in any form, is both a copyright violation and an academic integrity violation.

Note: for hypothesis testing problems, you must show how you calculated your test statistic. You do not need to show work for the step of going from the test statistic to the p-value, as this step comes from tables or a calculator. You should always write a concluding sentence in which you explain your conclusion in the context of the problem.

Note: for hypothesis testing problems, you must show how you calculated your test statistic. You do not need to show work for the step of going from the test statistic to the p-value, as this step comes from tables or a calculator. If you are using tables rather than a calculator, it is acceptable just to report an interval containing the p-value. You should always write a concluding sentence in which you explain your conclusion in the context of the problem.
