Answer:
H₀: μ ≤ μ H₁: μ > μ
Step-by-step explanation:
Hello!
If battery 1 lasts longer than battery 2, and all the batteries of population 1 and population 2 are built using the same method, then you could say that the population mean of the lifespans of batteries 1 are longer than the lifespan of batteries 2. Symbolically: μ₁ > μ₂
This would be your alternative hypothesis.
The null hypothesis is:
H₀: μ₁ ≤ μ₂
Then the correct answer is number 5
Looked for exercise's Options
H₀: μ ≥ μ H₁: μ < μ
H₀: μ ≤ -μ H₁: μ > -μ
H₀: μ ≥ -μ H₁: μ < -μ
H₀: μ = μ H₁: μ ≠ μ
H₀: μ ≤ μ H₁: μ > μ
20x 10 to the third power equals 20000
Answer:
1
Step-by-step explanation:
9-7 = 2 (-2)
1-3 = -2
-2/-2 = 1
n/4 because all it wants is a number which is expressed by n divided by 4
Answer:
As the number is a prime number. Therefore, option 'c' is true.
Step-by-step explanation:
Let us take the number 7 and divide it by 4
We know that
as
so the remainder is 3. ∵ 
As 7 is a prime number, and when we divide the prime number 7 by 4, we get the remainder 3.
Thus, the number is a prime number. Therefore, option 'c' is true.
