Answer:
4.95238095238= x
Step-by-step explanation:
-87= 3(6-7x)
-87= 17-21x
-17 -17
-104= -21x
/-21 /-21
4.95238095238= x
A point estimate of the mean is a number that is used to approximate the true value of said population parameter.
To find the point estimate of the mean we will use the associated sample parameter X-bar.
Since Xbar is an unbiased estimator of μ, then:
μ_X-bar = μ.
X-bar = 16.6
So:
The estimate of population mean = X-bar = 16.6
Answer:6 1/2
Step-by-step explanation:1/2+3 1/2+2 1/2
Add all the halves (1/2)
1/2+1/2+1/2=1 1/2
Then add the 3 and 2 in front of the fraction.
3+2=5
So, 1 1/2+5=6 1/2
