Find the critical value from the Studentized range distribution for: (a) = 0.05, n = 16,

Find the critical value from the Studentized range distribution for:
(a) α = 0.05, n = 16, k = 7
(b) α = 0.05, n = 30, k = 6
(c) α = 0.01, n = 42, k = 4
Use q0.01,40,4 since q0.01,42,4 is not in the table.
(d) Find the critical value from the Studentized range distribution for H0: µ1 = µ2 = µ3 = µ4 = µ5 = m6, with n = 46, a = 0.05.
