Answer:
We want to test if the if p1 = the proportion of people who have myopia in 2019 is equal to p2 = proportion of people who have myopia in 2010 (alternative hypothesis) , then the system of hypothesis are:
Null hypothesis: ![p_1 = p_2](https://tex.z-dn.net/?f=p_1%20%3D%20p_2)
Alternative hypothesis: ![p_1 = p_2](https://tex.z-dn.net/?f=%20p_1%20%3D%20p_2)
And the best option would be:
b. H0:P1=P2; Ha:P1≠P2
Step-by-step explanation:
For this case we have the following info given:
the myopia cases in 2019
the sample size in 2019
estimated proportion of myopia cases in 2019
the myopia cases in 2010
the sample size in 2010
estimated proportion of myopia cases in 2010
And we want to test if the if p1 = the proportion of people who have myopia in 2019 is equal to p2 = proportion of people who have myopia in 2010 (alternative hypothesis) , then the system of hypothesis are:
Null hypothesis: ![p_1 = p_2](https://tex.z-dn.net/?f=p_1%20%3D%20p_2)
Alternative hypothesis: ![p_1 = p_2](https://tex.z-dn.net/?f=%20p_1%20%3D%20p_2)
And the best option would be:
b. H0:P1=P2; Ha:P1≠P2
And we can conduct a two sample z proportion test in order to verify the hypothesis.
The answer to that question is b
The area of a 2D form is the amount of space within its perimeter. The total surface area of the square pyramid is 40 meters².
<h3>What is an area?</h3>
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Henri built a lantern in the shape of a square pyramid. He wants to cover the entire pyramid with fabric. Therefore, the amount of fabric that Henri will need is equal to the total surface area of the square pyramid.
Total surface area = Area of the base + 4(Area of the triangle)
= (4m × 4m) + 4(0.5×4m×3m)
= 16 meters² + 24 meters²
= 40 meters²
Hence, the total surface area of the square pyramid is 40 meters².
