For each of the following scenarios, determine the appropriate critical value(s) for comp On the cover sheet, you should include the symbol(s), subscripts and value(s) (e.g., f_0.025, 12, 9 = 3.87 and f_0.975, 12, 9 = 1/f_0.025, 9, 12 = 0.2907).

Solution

a)

df = 20-2 = 18

alpha = 0.05/2 = 0.025

t critical =+/-2.101

b)

df= 25-2 = 23

alpha/2 = 0.025

X^2 = 38.076 and 11.689

c)

alpha = 0.10

Z = -1.28
