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...

In other words, is the six months post-pregnancy weight greater than their pre-pregnancy weight? Use a paired samples t-test to compare pst6wght (variable 1) and prewght (variable 2). This uses...
