The population was 4800 when the collection of population data began. Therefore, option C is the correct answer.
The given function is
where t is the number of years since the collection of the population data began.
We need to find which of the given option is a true statement.
<h3>How to solve exponential function?</h3>
An exponential function is defined by the formula
, where the input variable x occurs as an exponent. The exponential curve depends on the exponential function and it depends on the value of the x.
The exponential function is an important mathematical function which is of the form
.
We can evaluate the given function using
.
By comparing a given function with this formula we can say the population was 4800 when the collection of population data began is a true statement.
Therefore, option C is the correct answer.

Answer:
Step-by-step explanation:
Data given
20 13 21 18 19 22 19 15 12 12 18 21
We can calculate the sample mean and deviation with the following formulas:
![\bar X =\frac{\sum_{i=1}^n X_i}{n}](https://tex.z-dn.net/?f=%5Cbar%20X%20%3D%5Cfrac%7B%5Csum_%7Bi%3D1%7D%5En%20X_i%7D%7Bn%7D)
![s= \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}](https://tex.z-dn.net/?f=s%3D%20%5Csqrt%7B%5Cfrac%7B%5Csum_%7Bi%3D1%7D%5En%20%28X_i%20-%5Cbar%20X%29%5E2%7D%7Bn-1%7D%7D)
And we got:
represent the sample mean
population mean (variable of interest)
s=3.61 represent the sample standard deviation
n=12 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
Since the Confidence is 0.90 or 90%, the significance is
and
, the critical value would be given by
Now we have everything in order to replace into formula (1):
