HP 40g - Statistics Question 4

For the data below, I key in the values of t into column C1 and 100B(t) into column C2.

t: 2 4 6 8 10 12 14
B(t): 0.09 0.36 1.02 1.82 2.27 2.45 2.46

However, the logistic fit found by the graphic calculator does seems to have a good fit. The answer obtained is different from the answer of the book of Haese & Harris - Yr 12 Mathematical Studies Edition 2, page 169, Example 16 as well. Please take note of this matter and check if the logistic fit is suitable to be used for the students.
