) First, you will create a discussion board post where you solve a homework question *and*
provide an explanation for how you solved the question. Sometimes, the explanation may
be as simple as you used StarCrunch. If so, provide the specific function that you used in
StatCrunch. More often, you will find that you need to analyze the information that is given
in the problem and use definitions or techniques described in the instructional videos.
When this occurs, you will describe how you analyzed the problem and what
definition/technique you used. This will become natural with practice. This counts as your
first post of the week.2) For your second post, you will reply to one of your colleagues in the
class. In that reply, you will highlight the information in their explanation that you found
particularly helpful in understanding how they solved the problem. This could include the
language that they used in their explanation that made the explanation particularly clear or
it could include how they referenced the definitions that they used or the analysis that they
performed to solve the question.The goal is to develop your ability to explain how you solve
statistics questions by reading the explanations of your colleagues and learning from
them.Week 4:The number of alcoholic drinks per week is given below for adult men and

StatCrunch. If you haven’t used StatCrunch yet, then here is a video on Accessing
StatCrunch.If you want to use the shortcut that is in the homework to load the data, then the
problem is #12 from the homework. Otherwise, you can enter the data above by hand into
an empty StatCrunch spreadsheet – the video shows how to bring up an empty StatCrunch
spreadsheet).a. Compare the mean number of drinks for men and women. Interpret your
solution by explaining what your result means for the amounts that men and women drink.
Write your answer in your own words. Do not use the format from the homework. To show
your work, state the function you used in StatCrunch to calculate the mean.b. Compare the
standard deviation of the number of drinks of men and women. Interpret your solution by
explaining what your result means for the amounts that men and women drink. Write your
answer in your own words. Do not use the format from the homework. To show your work,
state the function you used in StatCrunch to calculate the standard deviation.c. Remove the
top two outliers from the data set for men, and compare the means again. What effect did

2. removing the outliers have on the mean? Interpret your solution by explaining what your
new result means for the amounts that men and women drink. Write your answer in your
own words. Do not use the format from the homework.d. What effect do you think
removing the top two outliers would have on the standard deviation? Explain why in your
own words. Do not use the format from the homework.
