My house is located at (1,1) and the store is located at (4,3) Each square is a mile. How far do I walk to get to the store?
Answer:
Correct option: (D).
Step-by-step explanation:
The hypothesis for testing whether there is a difference between the two population proportions is:
<em>H₀</em>: The population proportion of students who drive to school for R and S is same, i.e. <em>p</em>₁ = <em>p</em>₂.
<em>Hₐ</em>: The population proportion of students who drive to school for R was greater than that for S, i.e. <em>p</em>₁ > <em>p</em>₂.
The difference between the two sample proportion is,
And the <em>p</em>-value of the test is:
<em>p</em>-value = 0.114
The <em>p</em>-value is well defined as the probability, [under the null-hypothesis (H₀)], of attaining a result equivalent to or greater than what was the truly observed value of the test statistic.
We reject a hypothesis if the <em>p</em>-value of a statistic is lower than the level of significance <em>α</em>.
The <em>p-</em>value of 0.114 indicates that, assuming the null hypothesis to be true, the probability of obtaining a difference between the two sample proportions of at least 0.07 is 0.114.
The correct option is (D).
