Answer:
E: None of the above
Step-by-step explanation:
Hello!
The objective is to find out how much time it takes people to commute to work.
Two samples where taken and two hypothesis tests where made:
One:
Sample mean 71 min; p-value: 0.03
Two:
Sample mean 72 min; p-value: 0.06
You have to choose from the options, a possible pair of hypotheses used for these two tests.
The parameter of the study is the population mean μ.
In the statistic hypotheses, the parameters are given either a known population value or a suspected value. So all options including sample values are wrong.
As said before the objective of the survey is to "determine how much time people spend commuting to work" in other words, whether or not the population mean is equal to a certain value.
H₀: μ = μ₀
H₁: μ = μ₀
Where μ₀ represents the theoretical value of the population mean. As you can say the hypotheses pair is two-tailed, not one-tailed.
Then the correct answer is E: None of the above
I hope this helps!
Answer:
359
Step-by-step explanation:
6x3+18
18 to the second power is 324
10x3=30
30+5=35
324+35=359
Answer:
The intersection point of diagonals is (0.5,-4.5).
Step-by-step explanation:
The end points of first diagonal are p(-3, -2) and i(4, -7).
The end points of second diagonal are a(4, -2) and d(-3, -7).
If a line passing through two points, then the equation of line is
The equation of first diagonal is
.... (1)
The equation of second diagonal is
.... (2)
Add equation (1) and (2),
Put this value in (1).
The intersection point of diagonals is (0.5,-4.5).
Answer:
2
Step-by-step explanation:

7/10 x 8 = 5 6/10
15 5/8 - 5 6/10 = 10 1/40
10 1/40 / 7/10 = 14 9/28
so he can make 14 more bowls and 9/28 of another bowl so you round down to 14 complete bowls.
