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.
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:
When they ask in part a, "how
would you assign labels?" they merely mean what numbers would you assign
to the trees (such as 001 to whatever). I don't think you have to
explain how you would actually put the numbers on the trees. Paint them
on? Tie them on with a ribbon? Brand them on? Doesn't matter.
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 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. I tell you what experiments and observational studies are in Lesson 3.
