Suppose that 350 cervical cancer cases were identified and a random sample of women of the same age range who were admitted to t

he hospital included 500 eligible controls. After independent blood tests of all cases and controls, 90% of cases were positive for HPV antibodies while 63% of controls were positive for antibodies to the virus. What is the appropriate measure of association and its value? choose answer:
a)The ratio of the odds of exposure among cases and controls equal to 5.3

b)The ratio of HPV-exposed percentages equal to 1.4

c)The number of exposed cases divided by the number of exposed controls equal to 1.0

d)The number of nonexposed cases divided by the number of nonexposed controls equal to 0.2

Answer:

a)The ratio of the odds of exposure among cases and controls equal to 5.3

Step-by-step explanation:

Correct option is:

The ratio of the odds of exposure among cases and controls equal to 5.3

Solution:

Odds for cases=0.9/0.1=9

Odds for controls=0.63/0.37=1.703

Odds ratio=9/1.703=5.3

Hence the correct option is  a)The ratio of the odds of exposure among cases and controls equal to 5.3

Distributive property was the first property used in STEP 1, where -4 was distributed to -3x+ 2 resulting in the equation in STEP 1. Next in STEP 2, commutative property of addition no matter how 12x and 6x are arranged, when you add them together the result will be the same. 
*Take note that 12x and 6x are put together because they are like terms. 

For Steps 3 and 4, you will see that the addition property of equality was used in STEP 3. To keep the equation equal, you will add the same number on both sides.

STEP 4 uses Division property of Equality. Like Step 3, to keep both sides of the equation equal, you must divide both sides with the same number. It keeps the statement true by doing so. 

STEP 4 and 5 uses transitive property if you examine both as a whole. 
Transitive property assumes that if a = b and b = c, then a = c

If   18/18 (a) = 1 (b),  and x (c) = 18/18(a)  then, x (c) = 1 (b).

Sonja uses 8 of the 12 eggs in her dozen eggs to make a breakfast casserole. Olga uses 5/6 of a dozen eggs to make scrambled egg
GREYUIT [131]

Answer:

Olga will use 10 eggs, while Sonja will use 8, thus Olga will use more eggs.

Step-by-step explanation:

Given that Sonja uses 8 of the 12 eggs in her dozen eggs to make a breakfast casserole, while Olga uses 5/6 of a dozen eggs to make scrambled eggs, the following calculations must be performed to determine who uses more eggs:

Sonja = 8/12 = 0.666 x 12 = 8

Olga = 5/6 = 0.83333 x 12 = 10

Therefore, Olga will use 10 eggs, while Sonja will use 8, thus Olga will use more eggs.
