Answer: The margin of error =
Step-by-step explanation:
Given
Sample size (n) = 1000
Population proportion = 0.4
= 1 - confidence level
= 1 - 0.95
= 0.05
= 0.03
The margin of error change to to
Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>Initial population size is when t = 0</u>
- P(0) = 400(1.22)⁰ = 400(1) = 400
<u>The multiple of 1.22 is applied every year, so the ratio of change is:</u>
This is an exponential growth which represents 22% annual growth.
