aivan3 [116]

The table is not clear, so i have attached it.

Answer:

z statistic is -2.26

This is less than our alpha level,therefore we reject the null hypothesis and conclude that there is a significant difference in the proportion of homeowners between first generation and second generation Hispanic Americans

Step-by-step explanation:

From the attached table, we can see that;

first-generation hispanic americans; (N = 899 and percentage = 43%

second-generation hispanic americans; N = 351 and percentage = 50%

first-generation asian americans; (N = 2,684 and percentage = 58%

second-generation asian americans; N = 566 and percentage = 51%

Z-score formula in this case is;

z = (p1^ - p2^)/(√(p^(1 - p^)((1/n1) + (1/n2))

Where;

p^ = (p1 + p2)/(n1 + n2)

For, hispanic americans we have;

p1^ = 0.43 × 899 = 386.57

p2^ = 0.5 × 351 = 175.5

p^ = (386.57 + 175.5)/(899 + 351)

p^ = 0.45

Thus;

z = (0.43 - 0.5)/(√(0.45(1 - 0.45)((1/899) + (1/351))

z = -2.26

From z-distribution table, we have;

P-value = 0.01191

Since we have 2 samples, then probability = 2 × 0.01191 = 0.02382

This is less than our alpha level of 0.05,therefore we reject the null hypothesis and conclude that there is a significant difference in the proportion of homeowners between first generation and second generation Hispanic Americans.

If F(x)=3x-2/6 which of the following is the inverse of F(x)?
lana66690 [7]

Answer:

Step-by-step explanation:

I'm seeing that f(x) is

\frac{3x-2}{6}

What you do to find an inverse is switch the x and y coordinates and then solve for the new y.  Switching the x and y gives us:

x=\frac{3y-2}{6}

Now we have to solve for the new y.  Begin by muliplying both sides by 6 to get:

6x = 3y - 2 and

6x + 2 = 3y so

2x + 2/3 = y

To put it back into function notation:

f^{-1}(x)=2x+\frac{2}{3}

Scientists tag and release a group of salmon after they hatch. Later, they catch a sample of salmon that return to the river and
Liula [17]

The best prediction of the total number of tagged salmon in a sample of 2000 is 100.

<h3><u>Predictions</u></h3>

To determine what is the best prediction of the total number of tagged salmon in a sample of 2000, the following calculation must be performed:

  • 800 = 40
  • 2000 = X
  • 2000 x 40 / 800 = X
  • 80000 / 800 = X
  • 100 = X

Therefore, the best prediction of the total number of tagged salmon in a sample of 2000 is 100.

In the diagram below, lines a and b are parallel and cut by transversal, t. If angle 3 is 120 degrees, find the measure of angle
Vlad1618 [11]

Lines a and b are parallel and cut by the same transversal, t. Since we know these lines are parallel, we can find the measure of angle 7 quite easily.

Angles 3 and 7 are corresponding angles, which means that the two angles are in the same relative position. Thus, they are equivalent.

Angle 3 = angle 7 = 120 degrees

The correct answer is C. 120.

Hope this helps!! :)
