Answer: x = 0
Step-by-step explanation: x+5=−5x+5
Add 5x to both sides.
x+5+5x=5
Combine x and 5x to get 6x.
6x+5=5
Subtract 5 from both sides.
6x=5−5
Subtract 5 from 5 to get 0.
6x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 6 is not equal to 0, x must be equal to 0.
x=0
We have to find the critical t value for 99% confidence level and sample size of 18.
Degrees of freedom = n - 1 = 17
α = 1 - 0.99 = 0.01
α/2 = 0.01/2 = 0.005
So, from the t table we have to check the value against the column 0.005 and for 17 degrees of freedom.
This value comes out to be 2.898.
So, <span>tα/2</span> = 2.898
1/6=0.16666666666666666666666666666 or
