Researchers determined that 60 Puffs tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Puffs users yielded the following data on the number of tissues used during a cold: x = 52 and s = 22 . Suppose the alternative we wanted to test was H1:  < 60 . The correct rejection region for  = 0.05 is:
 a. reject H0 if t > 1.6604 c. reject H0 if t > 1.9842 or Z < -1.9842.
  b. reject H0 if t < -1.6604 d. reject H0 if t < -1.9842.

Question 2

If Friedman test is applied to a data set that are generated from a randomized block experiment with 3 treatments and 5 blocks, then the rejection region at the 2.5 significance level is Fr > 12.8325.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
