Answer:
n = 50
A) show the sampling distribution of x, the sample mean average for a sample of 50 unemployment individuals.
We will use central limit theorem
So, mean of sampling distribution =
Standard deviation of sampling distribution =
B) What is the probability that a simple random sample of 50 unemployment individuals will provide a sample mean within one week of the population mean?
A sample mean within one week of the population mean means
So,
=
=
=
=0.9616-0.0384
=0.9232
The probability that a simple random sample of 50 unemployment individuals will provide a sample mean within one week of the population mean is 0.9232.
C) What is the probability that a simple random sample of 50 unemployed individuals will provide a sample mean within a half week of the population mean?
A sample mean within one week of the population mean means
So,
=
=
=
=0.8106-0.1894
=0.6212
The probability that a simple random sample of 50 unemployed individuals will provide a sample mean within a half week of the population mean is 0.6212
In the picture we can see the graph represents of the function f(x)=x²-2x+3 that is curve graph.
Given that,
We have to find the graph represents the function f(x)=x²-2x+3.
We know that,
The quadratic function is f(x)=x²-2x+3.
This is a vertical parabola open downward
The vertex is a maximum
We know,
A vertical parabola's equation in vertex form is equal to
y= a(x-h)²+k
where
a is a coefficient
(h,k) is the vertex
Here
a=1
(h,k)=(0,3) is vertex
The y-intercept is the point (0,3) is value of y when the value of x is equal to zero (is the same point that the vertex)
The x-intercepts are the points is values of x when the value of y is equal to zero
Therefore, In the picture we can see the graph represents of the function f(x)=x²-2x+3.
