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


    PS 1: due Thursday 9/5 by 3:00pm

    Ch 3: 1, 25, 28
              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,
              and "brief report" means a paragraph or so

    Ch 5: 10, 20, 39, 50

    Ch 15: 13, 52, 59
              In 59, be as specific as possible
    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)


    PS 4: due Thursday 10/3 by 3:00pm

    Ch 18: 7, 11, 17, 20, 38
              For 17, comment on each -- what is wrong with most (or all) of
              them? For 38, notice specific questions on top of right column

    Ch 19: 14, 16, 19

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


    PS 6: due Thursday 10/17 by 3:00pm

    Ch 20: 66, 70, 78

    To clarify problem 13, the study used LFPR statistics from the same 19 randomly selected cities for both years       
      The .csv files containing the data for 20.66, 21.24, 21.26, and 21.34 are on OnCourse


    PS 8: due Thursday 10/31 by 3:00pm

    Ch 24: 5, 6, 10, 21, 22
    For (10c), think of Tukey's multiple comparisons method rather than Bonferroni's. For 21 and 22, do part (d), it is not optional
    The .csv files containing the data for 24.21 and 24.22 are on OnCourse


    For Thursday 11/7

    No problem set due Thursday because of exam that day
    Problems on the new Chapters are contained in the Study Guide
    Also prepare for the new Stats in the News portion of the exam (will be OnCourse, once it's ready)


    PS 9: due Thursday 11/14 by 3:00pm

    Note that since this problem set covers an extra day of class, it's a little longer than usual

    Ch 25: 11, 15, 22, 26
    Ch 22: 11*, 12*, 19, 33(e)-(g), 35, 47

    *For problems 22.11 and 22.12, combine the chi-square test of homogeneity and the chi-square test of independence into one option, so your choices are:
