Question
A random sample of 80 University of Missouri sophomores showed that 36 were planning to live off-campus next semester. Suppose that we are interested in forming a 99.7 percent confidence interval for the proportion of all Mizzou sophomores who are planning to live off-campus next semester.
Note that
3680=0.453680=0.45
and
(0.45)(1−0.45)80‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√=0.0556214886532175(0.45)(1−0.45)80=0.0556214886532175
NOTE: Where appropriate, express your answer as a proportion (not a percentage). Do not round during intermediate steps. If you round an answer, make sure you do so correctly and keep at least three decimal places.
(a) The estimate is: .
(b) The standard error is:
(c) The multiplier is:
