Answer:
Kindly check explanation
Step-by-step explanation:
The hypothesis :
H0 : μ = 3000
H0 : μ ≠ 3000
The test statistic :
(xbar - μ) ÷ (s/√(n))
xbar = 3500
μ = 3000
σ = 300
n = 30
(3500 - 3000) ÷ (350/√(30))
Test statistic = 7.824
Df = 30 - 1 = 29
Tcritical at 0.01 = 2.462
Test statistic > critical value ; we reject H0 ; and concluded that there is significant evidence that
μ ≠ 3000

Answer:
<u>92 feet.</u>
Step-by-step explanation:
Given:
The length of the garden needs to be 22 feet longer than the width of the garden.
The perimeter of the fence is a total of 324 feet
Question asked:
What will the length be of garden ?
Solution:
As length of the garden needs to be 22 feet longer than the width,
<u>Let width</u> = 
Then,<u> length </u>will be = 
As here perimeter of the fence is given, we can find length and width of garden by using:
Perimeter of rectangle = 

Subtracting both sides by 44

Dividing both sides by 4

Width =
= 70 feet
Then, length will be =
= 70 + 22 = 92 feet
Therefore, the length of the garden will be 92 feet.
