This
quiz is administered via Canvas & consists of 15
question multiple choice questions. It is timed at 20
minutes maximum. You will have one attempt to complete
the quiz. The quiz will become available on September

pm. Take note of this window of opportunity to

You are
on your HONOR to complete this assignment without assistance
from other students, outside websites, outside AI programs,
or other internal or external entities.
Topics you can expect to
see on the quiz:
1. How
does altering the sample size &/or the confidence level
effect the width of
a C.I.
2. Be
able to calculate a C.I. given mean, sample SD, & a
confidence level - including
small sample sizes (i.e., n<30) & larger sample sizes
(i.e., n>30)
3. Know
when to use a t value opposed to a z value when constructing
a C.I.
4. Be
able to give a practical interpretation of a C.I.
- for example a 90% C.I. for average salaries was
constructed we can say that
"We are 90% confident that the mean salary of all CEO's
falls in that C.I."
5. What
are the necessary assumptions for a C.I. to be valid
6. What
happens
to a C.I. if you use a z value instead of a t value
7. Given
a C.I., the mean, the sample SD, & the sample size, what
is the associated
confidence level
- this type of problem can also be asked about sample
size or sample SD when
all the other statistics/data are presented (i.e., back
solve for a variable in
the context of a C.I.)
