Question
A sample of size 20 yields a sample mean of 23.5 and a sample standard deviation of 4.3. Test H0: Mean 25 at = 0.10.
A sample of size 20 yields a sample mean of 23.5 and a sample standard deviation of 4.3.
Test H0: Mean 25 at = 0.10. HA: Mean < 25. This is a one-tailed test with lower reject region bounded by a negative critical value.
A.Pvalue 0.068. H0 rejected. Conclude mean < 25
B.Pvalue 0.932. H0 not rejected. Conclude mean 25
C.Pvalue 0.135. H0 not rejected. Conclude mean 25
D.None of the answers are correct.
