Discussion:
Q: A paired difference experiment produced the following results
a) Determine the values of z for which the null hypothesis, m1 -m2 = 0, would be rejected in favor of the alternative hypothesis, m1 - m2 < 0. Use a = 0.10
b) Conduct the paired difference test described in part a. Draw the appropriate conclusions.
c) What assumptions are necessary so that the paired difference test will be valid.
d) Find a 90% confidence interval for the mean difference.
