Suppose that a health magazine reports that a man’s weight at birth has a significant impact on the chance that the man will suffer a heart attack during his life. A statistician analyzes a data set from a sample of 798 men, and produces the pivot table and histogram shown below. Determine how birth weight influences the chances that a man will have a heart attack
The above pivot table shows counts (as percentages of row) of heart attack versus birth weight, where birth weight has been grouped into categories. The percentages in each category with heart attacks have then been plotted versus weight at birth as shown in the histogram. It appears that the likelihood of a heart attack is greatest for light babies, and then decreases steadily, but increases slightly for the heaviest babies.
