Study Lesson 3: Designing Samples and Experiments in the current edition of my book, if you have it, to prepare for this assignment. Note that, in older editions of my study book, this was Lesson 4.
 
Thankfully, there is no JMP needed for this stuff.
 
Question 1
Good luck guessing the exact word they want.  Note that sometimes it will be more than one word you have to put in the blank.
 
Question 2
Note non-response rate is just the total number of non-responses divided by the total number of emails sent out.  Response rate would be the total number of responses divided by the total number of emails sent out.  These rates could be changed into percentages but the question wants them left as decimals.  DO NOT STATE YOUR ANSWER AS A PERCENTAGE.
 
Question 3
You will need Table B to help answer this question.  That is in the textbook or can be downloaded from the resources section of Stats Portal.  Here is a link where you can download the table immediately, if you prefer:
Table B
 
When they ask in part a, "how would you assign labels?" they merely mean what numbers would you assign to the units.  They merely want you to explain how many digits each number you assign will have.  Like my example at the start of Lesson 3, where I have 700 people in my population, so I assign them the numbers 001, 002, up to 700.  The largest number in the population dictates how you will assign numbers (labels).
 
Question 4
When they ask you what the number in bold is, all they want you to say is that it is either a parameter or a statistic.  I define what those two things are at the start of Lesson 4 (Density Curves and the Normal Distribution) in my study book (lesson 2 if you have an older edition).  Parameters are for populations, statistics are for samples.
 
Question 5
A sample survey is just that, a survey where you are asked to answer a bunch of questions.  For example, opinion polls are sample surveys.  I tell you what experiments and observational studies are in Lesson 3, question 6. Many sample surveys can also be observational studies.  That's what they mean by "observational study that is not a sample survey."  In other words, if they are just conducting an opinion poll or the like, say it is a sample survey, even if you think it is also an observational study.
