The Porosity of a 3D printed knee implant is an important
quality characteristic for the product designers of a medical
device manufacturer. A random sample of 20 3D printed parts were
collected and the Porosity of those parts were measured with
X⎯⎯⎯=153.7 and s=11.5. What conclusion can you draw about this
experiment?
options:
a)
A calculated Test Statistic almost equal to zero will result in
accepting the alternative hypothesis
b)
A p-value of 0.0134 will result in accepting the null hypothesis
for α=0.05
c)
If the calculated Test Statistic gets a value of 1.44, then we
have enough evidence to reject the alternative hypothesis for a
two-tailed hypothesis test and α=0.1
d)
A really small p-value, almost equaling to zero, will result in
rejecting the null hypothesis.
e)
If the calculated Test Statistic gets a value of 1.44, then we
can reject the null hypothesis for a right-tailed hypothesis test
and α=0.1
