Hi, this is my question:

The height,s, of 50 sage seedlings is measured.

The table summarises the results.

Attachment 16513

A) draw a histogram to represent the height of the sage seedlings.

I HAVE DONE THIS!

B) calculate the MINIMUM possible range for the heights of the sage seedlings.

how would i do part B)? would it be 12-1=11?

thanks for you help!
