?
A: Make a logistic model of the height H, in inches, at age t years. Note: Thus far you are not given sufficient information to determine the value of r in the expression 
. Just leave that term as a variable.
?
B: In the model from part A we think of restricting the age to 15. That corresponds to putting 
in the formula, so H is a function of r. Make a graph of H versus r with . You may assume that r is no larger than 1.
?
C: Use your graph in part B to determine for what value of r the person will reach 90% of adult height at age 15.
?
D: Use the information you found in part C to make a logistic model of height versus age.
