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
Area of circle = πr² = 3.14×4² = 50.24m²
The best approximation is C.
Answer:
b = 2
Step-by-step explanation:
Given
2b + 5 = 9 ( subtract 5 from both sides )
2b = 4 ( divide both sides by 2 )
b = 2
