You wish to test the following claim (H1) at a
significance level of a =
0.05.
Ho:µ = 75.5
H1:µ < 75.5
You believe the population is normally
distributed, but you do not know the
standard deviation. You obtain a sample of
size n =
12 with mean = 67.4 and a
standard deviation of s = 12.7.
What is the test statistic for this sample?
(Report answer accurate to three decimal
places.)
test statistic =
What is the p-value for this sample? (Report
answer accurate to four decimal places.)
p-value =
