the mean is seventeen percent, and the margin of error is
0.035.
(Express answers as decimal numbers to 3 places.)
| lower limit | |
| upper limit |
Homework Answers
Solution,
Given that,
sample mean = 
= 0.17
Margin of error = E = 0.035
±
E
= 0.17 ± 0.035
= ( 0.135, 0.205 )
lower limit = 0.135
upper limit = 0.205
