Answer:
95% confidence interval for the mean μ is (6,14)
The Population mean μ lies between ( 6, 14 )
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given random sample 'n' = 1200
95% confidence interval for the mean μ is determined by

Level of significance = 95% 0r 0.05
Z₀.₀₅ = 1.96
= 10 ± 4
Mean of the small sample = 10
95% of confidence intervals are
( 10 ±4 )
( 10 -4 , 10+4)
( 6 , 14 )
95% confidence interval for the mean μ lies between ( 6, 14 )
Answer:
2/6 or 1/3
Step-by-step explanation:
Answer: A(x) = 15 ft + 2x
EXPLANATION
Given,
The dimension of the rectangular garden is 20 ft by 15 ft.
Dimension of a rectangle is written as Length by Width
This implies that,
Length of the garden = 20 ft
Width of the garden = 15 ft
The garden has a walk around it of width x.
The combined width of the garden = Width of garden + 2x
[we are adding twice the width of the walk because it is
around the garden (this means it will add to the width of the garden on both the left and right sides)]
Combined width of the garden, A(x) = Width of garden + 2x
Since width of the garden = 15 ft
A(x) = 15 ft + 2x
