Define the size of the sample
Assign to each student a unique number.
using a random number generator, generate enough different numbers to fill the sample.
Each of these numbers corresponds to a unique student, so now you have a complete sample of random selected students.
This sample can not be biased in any way.
Answer with Step-by-step explanation:
f(1) = 160 and f(n + 1) = –2f(n)
⇒ f(2)= -2×f(1)
= -2×160
= -320
⇒ f(3)= -2×f(2)
= -2×(-320)
= 640
⇒ f(4)= -2×f(3)
= -2×640
= -1280
Hence, Value of f(4) is:
- 1280
The answer would be <span>1.800.000 humans</span>
