You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size
n
=
121
n
=
121
with mean
M
=
68.4
M
=
68.4
and a standard deviation of
S
D
=
16.1
S
D
=
16.1
.
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic = Incorrect
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value = Incorrect
