In the Health ABC Study, 543 subjects owned a pet and 1977 subjects did not. Among the pet owners, there were 293 women; 975 of

True [87]

Answer:

The proportion of pet owners who were women is 0.540.

The proportion of non-pet owners who were women is 0.493.

Step-by-step explanation:

The data provided is summarized in the table below.

Pet Owners Non-Pet Owners TOTAL

Men 250 1002 1252

Women 293 975 1268

TOTAL 543 1977 2520

Denote the events as follows:

W = a subject is a women

P = a subject is a pet owner

The probability of an event, say E, is defined as the ration of the favorable outcomes of E to the the total number of outcomes of the experiment.

P (E) = n (E) ÷ N

Here,

n (E) = favorable outcome

N = total number of outcomes

(1)

The conditional probability of an event B given that another events A has already occurred is:

P (B | A) = n (A ∩ B) ÷ n (A)

Compute the probability of a pet owner being a women as follows:

P (W | P) = n (W ∩ P) ÷ n (P)

= 975 ÷ 1977

= 0.5396

≈ 0.540

Thus, the proportion of pet owners who were women is 0.540.

(2)

Compute the probability of a non-pet owner being a women as follows:

P (W | P') = n (W ∩ P') ÷ n (P')

= 293 ÷ 543

= 0.4932

≈ 0.493

Thus, the proportion of non-pet owners who were women is 0.493.

You're just simply going to use the equation for surface area which is
$SA=2LW+2LH+2WH$ ( $or (2 * length * width) + (2* length * height) + (2* width * height)$ ) so you're going to plug in and then solve to get the inches squared of all the sides that Erin would cover with the contact paper.
Once you get that number you're going to multiply it by .08 to get the price.
