A researcher at a major clinic wishes to estimate the proportion of the adult population of the United States that has sleep dep
Thepotemich [5.8K]

Answer: n = 600.25 ≈ 601 ( sample size)

the minimum sample size of the adults in United State who have sleep deprivation  is 601

Step-by-step explanation:

Given that;

the confidence level = 95% = 0.05

the Margin of error E = 4% = 0.04

∴  level of significance ∝ = 1 - C.L

∝ = 1 - (95/100)

= 0.05

Z∝/2 = 0.05/2 = 0.025

Z-critical value at 95% confidence level is OR level of significance at 0.025 = 1.96 (z-table)

Now to calculate the sample size, we say

n = (Z(critical) / M.E )² P ( 1 - P)

now we substitute

n =  (1.96 / 0.04)² × 0.5 ( 1 - 0.5)

n = 2401 × 0.5 × 0.5

n = 600.25 ≈ 601

Therefore the minimum sample size of the adults in United State who have sleep deprivation  is 601

Elodia [21]
<span>The sum of the angle of a triangle is 180 degrees. It is mentioned that Hannah drew a pattern of equilateral triangles. Equilateral triangle has three equal sides. Also, its angles are the same, having 60 degrees at each corner of the triangle. The answer is a. Letter b does not qualify to be an equilateral triangle because 120 degrees times 3 is greater than 180 degrees. Letter c and d exceeds the total number of angles at 180 degrees.</span>
