Question:

Consider the following sample of 10 measurements. 8.416.9 15.8 12.5 10.3 4.9 12.9 9.8 23.7 7.3 Use these data to conduct each of the following sign tests using the binomial tables (Table I, Appendix D) and a = .05:

a. H0: h = 9 versus Ha: h 7 9

b. H0: h = 9 versus Ha: h ≠ 9

c. H0: h = 20 versus Ha: h 6 20

d. H0: h = 20 versus Ha: h ≠ 20

e. Repeat each of the preceding tests using the normal approximation to the binomial probabilities. Compare the results.

f. What assumptions are necessary to ensure the validity of each of the preceding tests?
