Answer:
E(X ¯)=210,000.
Step-by-step explanation:
A sampling distribution for samples of size n=49 from a population with means μ=210,000 and standard deviation σ=35,000, has the following means anda standard deviation:

If X ¯ is the mean sales price of the sample, it will have a mean value of E(X ¯)=210,000.
Answer:
Step-by-step explanation:
For problem #1 identify the coordinates of the point of intersection of the two lines. This point is (4, 2), and this is the solution to #1.
In problem #2 the lines never cross, and thus we conclude that there is no solution.
Answer:
A number line going from 0 to 10. An open circle is at 7. Everything to the left of the circle is shaded.
Step-by-step explanation:
We have the following inequality:
-1.1x + 6.4 > -1.3
to solve it, we need to isolate x, as follows:
-1.1x > -1.3 - 6.4
-1.1x > -7.7
x < -7.7/-1.1 (notice that while dividing with a negative number, the sign changes)
x < 7
