Step-by-step explanation:
The statistical inference may be defined as the process of using the data analysis to infer the properties of an underlying distribution for a probability.
In the context, for testing the population proportion p, the following conditions are used to verify the inference procedures so as to make the statistical inferences :
-- data that are collected by a random assignment or by a random sample.
-- sample size should be less than 10% of population size.
-- The 
and the 
for the sample size 
as well as for the hypothesis proportion, 
Answer:
24 units ²
Step-by-step explanation:
In this problem, we are given the circumference of a triangle (after finding the perimeter) and want to find the area of a circle with that circumference. Since the area of a circle is a function based on its radius, we can use the circumference to find the radius to find the area.
First, we can figure out the perimeter of the triangle, which is equal to the sum of its sides. The perimeter is 6+4+7.21 = 17.21 units.
Next, the circumference of a circle is equal to π * diameter = π * 2 * radius. Using 3.14 for π and r for radius, we get
3.14 * 2 * r = 17.21
6.28 * r = 17.21
divide both sides by 6.28 to isolate r
r ≈ 2.74
Furthermore, to find the area from the radius, we can use
area = πr². Plugging 2.74 in for r, we get
2.74² * 3.14 = area
≈23.6, rounding up to 24 units ²
