Construct a 95% confidence interval to estimate the population
mean with x=103 and σ=32 for the following sample sizes.
a)
n
=
31
b)
n
=
46
c)
n
=
64
a) With 95% confidence, when n=31, the population mean is
between the lower limit of ___ and the upper limit of ___.
(Round to two decimal places as needed.)
b) With 95% confidence, when n=46, the population mean is
between the lower limit of ___ and the upper limit of ___.
(Round to two decimal places as needed.)
c) With 95% confidence, when n=64, the population mean is
between the lower limit of ___ and the upper limit of
___.
(Round to two decimal places as needed.)
