Answer:
The null hypothesis is that there is no difference in the mean number of male and female cats
H₀; μ₂ - μ₁ = 0
Step-by-step explanation:
The given parameters are;
The given percentage of male stray cat population = 50%
The given percentage of female stray cat population = 50%
The number of areas the researcher visits, n = 15
The number of stray male cats he finds = 11
The kind of test to be performed = Sign test
The significance level, α = 0.05
A) Therefore the null hypothesis is H₀; μ₂ - μ₁ = 0
The alternative hypothesis is Hₐ; μ₂ - μ₁ ≠ 0.
When a whole number is multiplied by 1,000 the product is the whole number with 3 zeros added behind it.
Answer:
A. Helps scientists track weather
Step-by-step explanation:
Have you seen those weather guys on TV showing clouds and stuff, they got them via satellite or at least if there are animations, those are possible because they can see what the clouds or other stuff look like via satellites.
10.) The lines that the angles are on are not parallel to each other. 11.) Angle 2 is also 60 degrees because they're corresponding angles. They're just on different lines but the place they meet the intersecting lines are the same. 12.) A real life situation that uses parallel lines are a rectangular room's walls that are parallel to each other.
