We can get two different equations from this:
3x = 18
and
3x = -18
So:
x = 6, x = -6
x = {6, -6}
X= c/3a - b/3a if I’m right.

Answer:
a) Standard error = 0.5
b) 99% Confidence interval: (19.2125,21.7875)
Step-by-step explanation:
We are given the following in the question:
Population mean = 20.50 mpg
Sample standard deviation = 3.00 mpg
Sample size , n = 36
Standard Error =

99% Confidence interval:

Putting the values, we get,
