# Trigonometry question watch

1. (Original post by Tygra)
Also I have a question concerning cumlative frequency.

I have a question using grams, and it says that the weight is correct to the nearest gram. Does this mean I have to change the intervals?

The first two intervals are 85-89 and 90-94.

As the question is stating to the nearest gram do it change the intrervals to 84.5-89.5 and 89.5-94.5??
Hmmmm

Depends what you are wanting to do

I would generally say yes
