HI, i still dont understand question 1 mainly because i don't know what the question is asking for?

[huuhwhat]

question, for 17:16 question 15
why did you use 3.75 and 1.835?
im curious as the question says calculate the upper bound, so wouldnt that mean we use the upper bound of all the values?
so that would mean using : 9.65 3.85 and 1.845 to do:
9.65 - 3.85 / 1.845
= 3.14
