A cohort study was undertaken to examine the association between high lipid level and coronary heart disease. Participants were classified as having either a high lipid level (exposed) or a low or normal lipid level (unexposed). Because age is associated with both lipid level and risk of heart disease, age was considered a potential confounder, and the age of each subject was recorded. The following data describes the study participants:Overall, there were 11,000 young participants and 9,000 old participants. Of the 4,000 young participants with high lipid levels, 20 of them developed CHD. Of the 6,000 old participants with high lipid levels, 200 of them developed CHD. In the unexposed, 18 young and 65 old participants developed CHD.1. Construct the appropriate two by two tables using the data given above. Be sure to label the cells and margins.2. Calculate the appropriate crude ratio measure of association combining the data for young and old individuals.3. Now, perform a stratified analysis and calculate the appropriate stratum-specific ratio measures of association. What are they?4. Do the data provide evidence of effect measure modification on the ratio scale? Justify your answer.
Answers
Step-by-step explanation:
1. Is a table which is contained in the attachment
2. The crude ratio measure
= 4000x3000+20*5800/7000*6000+200*3980
= 12000000+116000/42000000+796000
= 12116000/42796000
= 0.283
3. Stratum specific for high lipid
= 12000000/42000000
= 0.285
= 0.29
Stratum specific for chf
= 116000/796000
= 0.145
= 0.15
4. High lipid has higher risk than chd from the solution here

Step-by-step explanation: Can I get brainliest? Thanks!
Total distance = 1930
Car speed avg = 60 miles per hour
Plane speed avg = 350 miles per hour
Time = 8 hours
(60*3)+(350*5)=1930 (Try combinations of 3+5, 4+4, 2+6 etc)

A portion of a roadmap is shown in the figure. What is the measure of angle p.
Answers
Step-by-step explanation:
Per our conceptual understanding, when two parallel lines are cut by a transversal line then their corresponding angles are equal.
So, If PQ and RS are two parallel lines and line L1 as shown is the transversal line then the corresponding angles are equal.
Hence, ∠1 = ∠2Or, c0 = 1800 – c02c = 180c = 90°
Therefore, if we get c = 90° then PQ and RS are parallel else PQ and RS are not parallel,
With this understanding, let us now analyse the individual statements.
Step 3: Analyse Statement 1
“b = 2a”
Per conceptual understanding, the sum of all the angles of a triangle is 180.
Hence, a + b + c = 180a + 2a + c = 1803a + c = 180
However, from the above equation, we can get many values of a and c.
Hence, statement 1 is not sufficient to answer the question.
Step 4: Analyse Statement 2
“c = 3a”
a + b + c = 180a + b + 3a = 180b + 4a = 180
However, from the above equation, we can get many values of a and b.
Hence, statement 2 is not sufficient to answer the question.Step 5: Combine Both Statements Together (If Needed)
From statement 1:
3a + c = 180
From statement 2:
c = 3a
Combining both the statements:
3a + 3a = 180.
From the above equation, we can find the value of a. Then we can find c.
Since we could find the answer by combining both the statements, option C is the correct answer.

Answers
Answer:
680
Step-by-step explanation:
add al you can add all of them and then my total came to 67 7.64 rounded to the nearest should be around 680
The total expenses for the month including electric bills, TV streaming service and rent is $677,6.
What is summation?Summation is basically the result obtained by addition of all the numbers whose summation is to be obtained. The symbol used is ∑ for summation.
How to calculate total expenditure?The expenditures done by Peter who lives in an apartment are:
Electric bill=$34.80
TV streaming service=$27.99
Rent=$614,85
Total expenditure incurred by Peter on electric bill, TV streaming service and rent =34.80+27.99+614.85
=$677.64
After rounding off we will get $677.6.

The following function describes the number of employees working at a company, In thousands, where trepresents the number of years since the company revised the benefits package.
f(t) = 1.5(0.90)^t
Answers
Consider the missing part of the question is "Select the correct statement.
A. The number of employees is increasing by 50% every year.
B. The number of employees is decreasing by 10% every year.
C. The number of employees is decreasing by 90% every year.
D. The number of employees is increasing by 90% every year."
Given:
The function is:
[tex]f(t)=1.5(0.90)^t[/tex]
Where, f(t) is the number of employees working at a company, in thousands and t is the number of years since the company revised the benefits package.
To find:
The correct statement from the given options.
Solution:
The general exponential decay model is:
[tex]f(t)=a(1-r)^t[/tex] ...(i)
Where, a is the initial value, r is the rate of decay and t is the number of years.
We have,
[tex]f(t)=1.5(0.90)^t[/tex]
It can be written as
[tex]f(t)=1.5(1-0.10)^t[/tex] ...(ii)
From (i) and (ii), we get
[tex]a=1.5,r=0.10[/tex]
The initial value is 1.5 and the rate of decay is 0.10 or 10%. It means the number of employees is decreasing by 10% every year.
Therefore, the correct option is B.

Christopher has a stick that he has marked out in tenths. He has to break the stick into three pieces of which no two pieces can have the same length. Give three equations that show different ways in which he could break the stick.
Answers
The relationship between the three pieces is such that, their
sum is the length of the given stick.
Correct response:
Three equations that show different ways in which he can
break the stick of length l based on a unit length x are;
l = x + 2·x + 3·xl = x + 5·x + 8·xl = 3·x + 2·x + 6·xHow to write equations of three variables that have the same total sum?Given parameters are;
The number of pieces into which Christopher has to break the stick = 3 pieces
Length of a piece ≠ The length of the other pieces
Required:
Three equations that shows the different ways Christopher can break the stick.
Solution:
Let l represent the length of the stick, let x, represent a unit
length, and let, A, B, and C, represent the length of the pieces.
Three possible equations that can be written using multiples of x are;
l = x + 2·x + 3·xWhere;
The the relationship between the lengths of the pieces are;
A = x ≠ B = 2·x ≠ C = 3·x
[tex]x = \mathbf{ \dfrac{l}{6}}[/tex]
l = x + 5·x + 8·xA = x ≠ B = 5·x ≠ C = 8·x
[tex]x = \mathbf{ \dfrac{l}{14}}[/tex]
l = 3·x + 2·x + 6·xWhere;
A = 3·x ≠ B = 2·x ≠ C = 6·x

Lydias hotel room number has three digits.The hundreds digit has a value of 40 Tens.The Tens digit is greater than 6. Which could be Lydias hotel room number?
Answers
Any 3 digit number can be expressed in the form of:
[tex](a*100)+(b*10)+(c*1)[/tex]
Where [tex]a, b, c[/tex] represent any natural number from 0 to 9.
We are told the hundreds number (this means [tex]a*100[/tex] in the expression above) is equal to the value of 40 tens, 40 tens is 400. Then, we know the digit in the tens is greater then 6, this means [tex]b>6[/tex] in the expression above.
So, there are multiple numbers the room number could be, namely:
[tex]400+(b*10)+(c*1)\\[/tex]
where [tex]b[/tex] can be 7, 8, or 9; and [tex]c[/tex] can be 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. So, there's 30 possible room numbers Lydia may be.
