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!
So, if we define a straight line<span> to be the one that a particle takes when no forces are on it, or better yet that an object with no forces on it takes the quickest, and hence</span>shortest<span> route </span>between two points<span>, then walla, the </span>shortest distance between two points<span> is the geodesic; in Euclidean space, a </span>straight line<span> as</span>
The inequality would be 3x(4)-5≤67; the solution is x≤6; the graph is attached.
To solve this, first multiply the coefficients of x:
12x-5≤67
Add 5 to both sides:
12x-5+5≤67+5
12x≤72
Divide both sides by 12:
12x/12 ≤ 72/12
x ≤ 6
E. 5/15 since you multiply the numerator and denominator by 5.
D. 2/3 since you divide the numerator and denominator by 3.
W. 15/24 since you multiply the numerator and denominator by 3.
J. 4/5 since you divide the numerator and denominator by 5.
C. 48/54 since you multiply the numerator and denominator by 6.
G. 24/21 since you multiply the numerator and denominator by 3.
T. 27/36 since you multiply the numerator and denominator 3.
Answer:
i don't know if this is correct, but i think you place 2 in the box.
Step-by-step explanation:
you need to try to find the closetest multiple to find the division answer. so whichever one is closer is the one you need to use. mulitpy 2 to see if that's gets you anywhere, but something times 2 will get you 702. because if it ends in 2,4, or 6 it's a factor of 2. i hope this helps, but i'm not sure!
