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
Answer:
r
Step-by-step explanation: its r
To find a you need to do Sin(44) x 7 / sin(96)
That equals about 4.89
Answer:
A=16000 B=16400
Step-by-step explanation:
1. You multiply 20,000 by .2 or 20%, because you are trying to find a part of the 20,000.
2. You get 4,000 dollars, that is 20% of 20,000. To find the sale price, you take the 20% away from 20,000, which would be 16,000 dollars. That would be your answer for the first part.
3. the sales tax is 2.5% of the sale price. Again, you multiply 16,000 dollars, your sales price, by .025 or 2.5%.
4. you would get 400 dollars. You add the 2.5% or 400 dollars because you have to pay the tax as well as the price. You would get 16,400 dollars.
