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 : ![\alpha=0.05](https://tex.z-dn.net/?f=%5Calpha%3D0.05)
Using student's t distribution table , the critical value for a two-tailed t-test will be :-
![t_{\alpha/2, df}=t_{0.025,26}=2.056](https://tex.z-dn.net/?f=t_%7B%5Calpha%2F2%2C%20df%7D%3Dt_%7B0.025%2C26%7D%3D2.056)
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 :-
![t_{\alpha, df}=t_{0.05,26}=1.706](https://tex.z-dn.net/?f=t_%7B%5Calpha%2C%20df%7D%3Dt_%7B0.05%2C26%7D%3D1.706)
The critical value for a one-tailed t-test = 1.706
I believe the answer is -25/6 :)
1.) expand
3x - 15 - 5x = 25 + 6x
2.) simplify
-2x - 15 = 25 + 6x
3.) add 2x to both sides
-15 = 25 + 6x + 2x
4.) simplify
-15 = 25 + 8x
5.) subtract 25 from both sides
-15 - 25 = 8x
6.) simplify -15 - 25 to -40
-40 = 8x
7.) divide both sides by 8
-40/8 = x
8.) x = -5
