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

To visit his grandmother, Luis takes a train 6.376.376, point, 37 kilometers and a car 5.455.455, point, 45 kilometers.
How many kilometers is Luis's journey in total?
Answers
Answer:
Luis traveled 11.82 km in total.
Step-by-step explanation:
The statement should say: To visit his grandmother, Luis takes a train 6.37 kilometers and a car 5.45 kilometers. How many kilometers is Luis's journey in total?
Hence, to find the total distance traveled by Luis we must add the distances of the train (6.37 km) and the car (5.45 km):
[tex] d = d_{t} + d_{c} = 6.37 km + 5.45 km = 11.82 km [/tex]
Therefore, Luis traveled 11.82 km in total.

How long did it take to get to the airport?
Answers
Answer:
It took 3 hours to get to the airport
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)
It took 3 hours to get to the airport

the domain represents the number of terms and it only has natural numbers
The domain for the nth term A(n) of the sequence 26, 39, 52, 65, 78 is discrete.
What is a discrete function?When the domain and range of a function are discrete sets of values rather than intervals, the function is said to be discrete.
The given sequence is 26, 39, 52, 65, 78.
Since, Domain represents the real sets of values,
In the given sequence, the number in the sequence is real.
Also, the sequence is a discrete set of values,
