Answer:
Step-by-step explanation:
From the information given, the population is divided into sub groups. Each group would consist of citizens picking a particular choice as the most important problem facing the country. The choices are the different categories. In this case, the null hypothesis would state that the distribution of proportions for all categories is the same in each population. The alternative hypothesis would state that the distributions is different. Therefore, the correct test to use to determine if the distribution of "problem facing this country today" is different between the two different years is
A) Use a chi-square test of homogeneity.
Yo answer to yo question is d
The statement EF=2.GF (Option A) and the statement
(Option C) are true for the ΔEFG.
<h3>What are trigonometric ratios?</h3>
The six trigonometric ratios of a right-angle triangle are Sin, Cos, Tan, Cosec, Sec and Cot. Trigonometric ratios are used to measure the sides of the right triangle.
Given that in ΔEFG, m∠E=30°, m∠F=60° and m∠G=90°.
Wow, sin 30°
⇒
⇒EF=2.GF
and sin 60°
⇒
⇒
Therefore, the statement EF=2.GF (Option A) and the statement (Option C) are true for the ΔEFG.
