Answer:
b. Hannah is likely to be incorrect because 9 is not contained in the interval.
Step-by-step explanation:
Hello!
Hannah estimated per CI the difference between the average time that people spend outside in southern states and the average time people spend outside in northern states.
The CI is a method of estimation of population parameters that propose a range of possible values for them. The confidence level you use to construct the interval can be interpreted as, if you were to calculate 100 confidence interval, you'd expect that 99 of them will contain the true value of the parameter of interest.
In this example, the 99%CI resulted [0.4;8.0]hs
Meaning that with a 99% confidence level you'd expect the value of the difference between the average time people from southern states spend outside than the average time people from northern states spend outside is included in the interval [0.4;8.0]hs.
Now, she claims that people living in southern states spend 9 more hours outside than people living in northern states, symbolized μ₁ - μ₂ > 9
Keep in mind that if you were to test her claim, the resulting hypothesis test would be one-tailed
H₀: μ₁ - μ₂ ≤ 9
H₁: μ₁ - μ₂ > 9
And that the calculated Ci is tow-tailed, so it is not valid to use it to decide over the hypotheses pair. This said, considering that the calculated interval doesn't contain 9, it is most likely that Hannah's claim is incorrect.
I hope this helps!
1) The process of cellular respiration takes place in the mitrochondria.
2) The process of photosynthesis takes place in the chloroplasts. Only plant cells and the cells of autotrophic protists and some bacteria undergo this process.
3) Phospholipids are lipids that consist of glycerol joined to two fatty acids and a phosphate group, which gives this molecule two nonpolar hydrophobic tails and a polar hydrophilic head. Phospholipids form bilayers that are used to make up biological membranes.
4)While there are definitely many more than 4 important molecules, I'm assuming the ones you are looking for are carbohydrates, proteins, Nucleic acids, and lipids.
5)A molecule is made up of two or more atoms held together by covalent bonds, whereas a compound is a substance containing two or more elements in a fixed ratio. Both molecules and compounds are made up of atoms/elements, however, compounds MUST be made up of two different kinds of elements, while molecules could consist of the same kind.
Hope this helps! :)
