Math 141 - Weekly Problem Sets - Fall 2019

Be sure to check back often, as assignments may change during the semester ( )
All chapter numbers refer 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 2: 18, 27, 43

Ch 3: 16. 37, 42

** PS 2: ** due Thursday 9/12 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

**PS 3: ** due Thursday 9/19 by 3:00pm

Ch 5: 10, 20, 39, 50As always, if/when you use Minitab Express, include the graphic or output in your explanation of the solution

Ch 15: 13, 52, 59

In 59, be as specific as possible

** 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 17: 11, 13, 16, 22, 38In 20,

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 19: 31a-d

Ch 20: 29, 34, 36, 39

** PS 7: ** due Thursday 10/24 by 3:00pm

Ch 20: 66, 70, 78The .csv files containing the data for 20.66, 21.24, 21.26, and 21.34 are on OnCourse

Ch 21: 13, 24, 26, 34

To clarify problem 13, the study used LFPR statistics fromthe same19 randomly selected cities for both years

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

Ch 24: 5, 6, 10, 21, 22The .csv files containing the data for 24.21 and 24.22 are on OnCourse

For (10c), think of Tukey's multiple comparisons method rather than Bonferroni's. For 21 and 22, do part (d), it is not optional

** 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

Ch 7: 16, 18, 20, 22, 73a-dThe .csv files containing the data for 7.73, 8.23, and 8.45 are on OnCourse
