Answer:
Step-by-step explanation:
The error in rounding a number is half of the unit of measure.
The number was rounded to the nearest 0.1 unit so the error is 1/2×0.1, which equals 0.05.
Now we add 3.7 and 0.05, which equals 3.75 and we also take 3.7 - 0.05, which equals 3.65
So, the error interval is:
Yes, I agree with the researcher's method. All the values of in the table correspond to the values of n by using their formula.
Step-by-step explanation:
Step 1:
If we substitute the values of n in the researcher's equation and we get the right values of , we can agree with the researcher's method.
The researcher's formula is Here
is the wombat population and n is the number of years.
Step 2:
When n = 1,
when n = 2,
when n = 3,
when n = 4,
when n = 5,
As all the values correspond to the values on the table, I agree with the researcher's method.
