Answer:

Test statistic =1.30

Step-by-step explanation:

Given that you are testing the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats.

                                             Men                Women            Difference

Sample size n                        60                     120

Proportion p_1, p_2              0.45                   0.35                 0.10

60 120 180

0.45 0.35 0.383333333

27 42 69

p = 0.3833

Std error for proportion difference = \bar p (1-\bar p)(\frac{1}{n_1}+\frac{1}{n_2})\\=0.3833(0.6167)(\frac{1}{60}+\frac{1}{120})\\=0.0769

Test statistic = \frac{p_1-p_2}{\bar p (1-\bar p)(\frac{1}{n_1}+\frac{1}{n_2})  }

=1.3008

=1.30

Using it's concept, it is found that his net worth is given by:

C) $1,052,662

<h3>What is the net worth of an individual?</h3>

It is given by the <u>sum of the individual assets subtracted by the sum of it's liabilities</u>.

In this problem:

  • The sum of his assets is of $178,000 + $1,055,000 = $1,233,000.
  • The sum of his liabilities is of $145,908 + $34,430 = $180,338.

Hence, his net worth is given by:

Net worth = $1,233,000 - $180,338 = $1,052,662.

Which means that option C is correct.

To polygons are said to be similar if all the corresponding angles of given polygons are equal.

In the given figure, it can be seen that in quadrilateral FSHB and quadrilateral KTWJ all the corresponding angles are equal.

∠F=∠K

∠S=∠T

∠H=∠W

∠B=∠J

Therefore, The given polygons are similar.

Hence, \text{quadrilateral FSHB}\sim\text{quadrilateral KTWJ }
