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!

The distribution of the pants and the shirts illustrates probability
The probability that he winds up wearing the white shirt and tan pants is 1/8
<h3>How to determine the probability?</h3>
The number of shirts is given as:
Shirts = 4
The number of pants is given as:
Pants = 2
The probability that he winds up wearing the white shirt and tan pants is then calculated as:
P = P(White shirt) * P(tan pant)
This gives
P = 1/4 * 1/2
Evaluate the product
P = 1/8
Hence, the probability that he winds up wearing the white shirt and tan pants is 1/8

Answer:
y = 9
Step-by-step explanation: this is because when x is 5 and is multiplied by -6 u get -30. from there u substratc -30 from -57 and get -27. so y is 9
