Identify the null and alternative hypothesis in the following scenario. To determine if battery 1 lasts longer than battery 2, t
Agata [3.3K]

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
