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.
  Indicate whether the statement is true or false
