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,
Step-by-step explanation:
it's obviously the equation is equals to zero,
-12x + 16 = 0
-12x = -16
-12. 12
like terms cancel each other to remaining with x
thus,
x = 4/3
<h2>AND</h2>
4x - 12 = 0
4x = 12
4. 4
like terms cancel each other to remaining (make x subject of the formula) with x
thus,
x = 3
