Compute the large sample and bootstrap 95% CI for mean calorie-adjusted total fat and saturated fat?

One issue is that people with higher total caloric intake generally have higher intakes of specific nutrients. One way to normalize nutrient intake for total caloric intake is to compute

Calorie-adjusted total fat = % calories from total fat = total fat (g) × 9 / total caloric intake. Similarly,

Calorie-adjusted saturated fat = saturated fat (g) × 9 / total caloric intake.
