Math 141 - Weekly Problem Sets - Fall 2019

    Be sure to check back often, as assignments may change during the semester
    ( )

    All chapter numbers refer Intro Stats, 4th Edition, by De Veaux, Velleman, and Bock

    Usually when we have problems that involve larger data sets, I will post the csv data files on OnCourse for you to import into Minitab Express


    Remember to follow the Problem Set Guidelines

              For each part of Problem 28, first hypothesize and describe
              your reasons for it, then you may use Minitab Express to
              calculate the standard deviation, then discuss what you learned

    Ch 4: 20, 31, 42
              For Problem 42: Can find the data file on OnCourse,

    As always, if/when you use Minitab Express, include the graphic or output in your explanation of the solution


    For Thursday 9/26

    No problem set this week.
    Problems on the new Chapters are contained in the Study Guide
    Also, do the pre-exam reflection linked to on the Reading assignment page (required, counts toward HW)
