Answer:
True
Step-by-step explanation:
Assume the following
Mean is represented by μ
Standard deviation by σ
Sample mean by x
Sample Size by n
Given that all possible values of a random variable calculated from a sample of size n with a population mean and standard deviation μ and σ, respectively, it's known that the sampling distribution of the sample mean x is its probability distribution.
Having said that, assume that a simple random sample of size n is drawn from a large population with mean μ and standard deviation σ, as stated above.
The sampling distribution of x will be distributed normally as long as the random variable is normally distributed.
Answer:
$189 in 9 hrs
Step-by-step explanation:
Use the difference of squares factorization - that for any numbers a and b, (a-b)(a+b)=a^2-b^2.
We have:
(x^2+1)(x^2-1)=x^4-1
In addition:
(x-1)(x+1)=x^2-1, so we have:
(x^2+1)(x+1)(x-1)
As our complete factorization.
