Answer:
-2
Assumption:
Find the value of x such that .
Step-by-step explanation:
Combine like terms:
This is not too bad too factor on the left hand side since 2(2)=4 and 2+2=4.
So we need to solve:
Subtract 2 on both sides:
Let's check:
0 was the desired output of .
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
Let's simplify step-by-step.
