Answer:
The t-score of 2.715 should be used
Step-by-step explanation:
Degrees of freedom ==> n - 1 ==> 38 - 1 ==> 37
to find 99% confidence interval, Hence,
Find t0.005 in front of 37 degrees of freedom,
Therefore the answer is, t-score = 2.715
Answer:
The slope is 0
Step-by-step explanation:
1. Subtract 6 from both sides now you would get..
2z=-10
Now divide each side by 2z and you get
z= -5
So the answer is -5
Answer:
Never
Step-by-step explanation:
If the slope is the same and the y-intercept is the same
They are the same line
2x + 5 = y is the same as 2x +5 = y
