Beginning with the basic balance equation, develop the open
system at steady state energy balance equation that is used for a
system with multiple inlet and outlet streams. Make sure to show
all steps and to define terms in words or by equations.
Show ALL work including steps used during computations
using formulas and diagrams when appropriate. Write a statement
explaining the meaning of your computations (conclusions) for all
problems- hypothesis tests and confidence intervals.
A researcher studied whether pregnant women who consumed more than
800 mg of caffeine per day had babies with a lower birth weight (in
lbs). The results are in the table below:
Caffeinated women’s babies weights
