Answer:
Step-by-step explanation:
We are to find critical values for the test given
a) df =16: Alpha = 0.01 and right tailed
Critical value= 2.583
b) df = 23-1 = 22: alpha = 0.1 and left tailed
critical= -1.717
c)df=31-1 =30: alpha =0.1: two tailed
t =1.697
Critical values can be obtained from critical t tables.
Left tailed will have negative sign and right tailed positive

Answer:
D = 
Step-by-step explanation:
given R = 
multiply all terms on both sides to eliminate the fraction
3R = 3D - T ( add T to both sides )
3R + T = 3D ( divide both sides by 3 )
D =
Answer:
x = 2
Step-by-step explanation:
10 -4 (2x-1) = -2(3-x)
10 - 8x + 4 = -6 + 2x
-10x = -6 -10-4
-10x = -20
x = -20/-10
x = 2
