A study was conducted at an American medical center and heart-attack incidents. A random sample of 30 heart-attack patients had their cholesterol levels measured two days after the attack. In addition, cholesterol levels were measured for a control group of 30 people who had not had a heart attack. The unitsf cholesterol measurement are mg/dL of blood. The two data sets are below regarding blood cholesterol levels DATA SET 1: HEART ATTACK GROUP (Assume that σ=46.63). 270 236 210 142...

Assume we are interested in the following events: this is everything that was given A: DCL > 260mm, B: TL > 180cm. Use the data and the concept of probability as a relative frequency to estimate the probabilities (relative frequencies) of these two events and of the joint event: A and B. Are A and B independent events? P(A) = P(B) = P(A and B) = Is this most accurately categorized as an observational or experimental study?...

In C++ Programming: Using a single for loop, output the even numbers between 2 and 1004 (inclusive) that iterates (loops) exactly 502 times. The outputted numbers be aligned in a table with 10 numbers per row. Each column in the table should be 5 characters wide. Do not nest a loop inside of another loop. Hint: First create and test the code that output the numbers all on one line (the command line will automatically wrap the output to new...
