Answer:
Confidence interval
And the margin of error would be:
Step-by-step explanation:
For this case we have the followig dataset:
DATA: 8.2; 9.1; 7.7; 8.6; 6.9; 11.2; 10.1; 9.9; 8.9; 9.2; 7.5; 10.5
We can calculate the mean and the deviation with the following formulas:
And replacing we got:
![\bar X= 8.98[/tex[tex]s = 1.29](https://tex.z-dn.net/?f=%20%5Cbar%20X%3D%208.98%5B%2Ftex%3C%2Fp%3E%3Cp%3E%5Btex%5Ds%20%3D%201.29)
The confidence interval for the mean is given by the following formula:
(1)
The degrees of freedom are given by:
The Confidence level is 0.95 or 95%, the value of significance is 
and 
, and the critical value would be 
Repplacing the info we got:
And the margin of error would be:
First, get the absolute values of the two numbers, which is:
|-6| = 6
|-3| = 3
next, subtract these numbers:
6 - 3 = 3
so the distance between -6 and -3 would be 3.
The equation of the function given as (x)= 5 * 2^x is an exponential function
<h3>How to determine the function type?</h3>
The equation of the function is given as
f(x)= 5 * 2^x
An exponential function is represented as
f(x) = a * b^x
Where
Initial value = a
Rate = b
This means that
a = 5
b = 2
Hence, the equation of the function given as (x)= 5 * 2^x is an exponential function
