The new study, published in the journal Circulation, finds that the risk of having a heart attack for men who routinely skip breakfast is 1.27 times the risk of having a heart attack for men who regularly eat breakfast. This means that the risk of having a heart attack for men who routinely skip breakfast is:

a.27% lower than for men who regularly eat breakfast. b.27% higher than for men who regularly eat breakfast. c.127% higher than for men who regularly eat breakfast. d.127% lower than for men who regularly eat breakfast.

Solution

If p shows the chance of having a heart attack for men who regularly eat breakfast then 1.27p shows the chance of having a heart attack for men who routinely skip breakfast. So risk increase is 1.27p - p = 0.27p. In percentage, ((0.27p) / p) * 100% = 27% .

That is the risk of having a heart attack for men who routinely skip breakfast is:  b.27% higher than for men who regularly eat breakfast.
