Answer:
Sample size= 956
Step-by-step explanation:
Hello!
You need to construct an 80% CI for the average life of batteries. (hours)
The study variable is:
X: Lifespan of a battery.
X~N(μ; σ²)
The population standard devition isσ= 8
The interval to estimate the population mean follows the structure:
"Point estimator" ± "margin of error"
X[bar] ± 
* (σ/√n)
X[bar] is the sample mean
* (σ/√n) is the margin of error of the interval (d)
Using the margin of error you can calculate the sample size:
d= * (σ/√n)
n= (σ* 
)²
n= 
n= 955.77 ≅ 956
I hope it helps!
Answer:
Original function:
f(x) = log2(x)
Transformed function:
f(x) = -log2(x - 1) + 2
The transformation process is to take f(x)=log2(x) and shift it to the right 1 unit and shift 2 units up. Then flip it down.
A log cannot have a negative value for an argument. Set the argument greater than zero.
x - 1 > 0
x > 1
The domain is all values greater than 1.
To find the range, use the domain.
Evaluate f(1.00001), f(2) , f(200), and f(2000)
Then use those values to determine the range.
