Answer: The critical value for a two-tailed t-test = 2.056
The critical value for a one-tailed t-test = 1.706
Step-by-step explanation:
Given : Degree of freedom : df= 26
Significance level :
Using student's t distribution table , the critical value for a two-tailed t-test will be :-
The critical value for a two-tailed t-test = 2.056
Again, Using student's t distribution table , the critical value for a one-tailed t-test will be :-
The critical value for a one-tailed t-test = 1.706
Answer:
Step-by-step explanation:
18x-2 = 17x +2
⇒18x-17x - 2 = 2
⇒x - 2 = 2
∴ x = 4
Answer:
Step-by-step explanation:
C, (1,7)
When you find the common denominator, multiply the numerator by the same number you do the denominator.
5: 1/6 - multiply both the numerator and denominator by 2: 1*2/2*6 = 2/12
2/12 < 5/12
6:
LCM would be 33
2/3 = 2*11 / 3*11 = 22/33
8/11 = 8*3 / 11*3 = 24/33
22/33 < 24/33
