8. Incorrect. The answer is
false, not true
The test can be formulated as follows
H0: μ=0.100
Ha: μ> 0.100
Under the H0, t0=(Xbar-μ0)(n)0.5/s=(0.106-0.100)*160.5/0.012=2.0
At 0.05 level of significance the decision rule is to reject H0
if t0.05,15 = 1.753 < t0,
where a=0.05 and there
are 16-1=15 degrees of freedom. Since t0=2, we reject H0
at the 5% level.
At 0.01 level of significance the decision rule is to reject H0
if t0.01,15 = 2.602 < t0,
where a=0.05 and there are
16-1=15 degrees of freedom. Since t0=2, we fail to reject H0
at the 1% level.
