Answer:
The correct option is (A).
Step-by-step explanation:
The <em>p</em>-value is well defined as the probability, [under the null hypothesis (<em>H₀</em>)], of attaining a result equivalent to or more extreme than what was truly observed.
From the provided options we can guess that the hypothesis was defined as follows:
<em>H₀</em>: There is no difference in the mean number of partners, i.e. <em>μ</em>₁ - <em>μ</em>₂ = 0.
<em>Hₐ</em>: There is difference in the mean number of partners, i.e. <em>μ</em>₁ - <em>μ</em>₂ ≠ 0.
The test is two tailed mean difference test.
A <em>z</em>-test or a <em>t</em>-test can be used to conclude the result.
In this case the <em>p</em>-value can be defined as the probability of obtaining a test statistic value equal to or more extreme that the results obtained from the sample, when the difference between the mean number of partners is 0.
Thus, the correct interpretation of the <em>p</em>-value is provided by statement (A).
Answer:
They do have the same solution
Step-by-step explanation:
In the first problem, you subtract 3/4 first. Next you would divide by 2/3. When you divide 7 1/4 by 2/3, you get 87/8. The only step in the second problem is to divide 87 by 8 (87/8).

No because a 2 digit divisor always has less digits than a 3 digit divisor
