1. Find the appropriate test statistic (if not
already given) and critical value. Then test the
following hypotheses assuming that the data
were from a simple random sam- ple and that
the sampling distribution of the sample mean
is normal:
e)HO :u<µ0 vs. H1 :u>µ0 ata=0.01,wheretstat
=3andn=4
f)HO :µzµ0 vs. H1 :u<µ0 ata=0.05,wheretstat
=3andn=9
g)HO :u=µ0 vs. H1 :4=µ0 ata=0.05,wherex
=-11,s2 =7,n=12,anduo =-9
h)HO :µ<µ0 vs. H1 :u>µ0 ata=0.05,wherex
=-11,s2 =7,n=12,andµ0 =-9
