Please help me correct the following sentences.

1. [STRIKE]In[/STRIKE] From the right-hand chart, we can see [that] it’s important for teenagers and children to get plenty of sleep. I would prefer to use 'that', but it's not essential.
2. People of all ages must sleep for at least 7 to 8 hours a day. :up: But it'd sound more natural like this: '...need at least 7 to 8 hours' sleep [every day]'.
3. But in the left-hand chart, we find [that] most people sleep less than 8 hours.

In Br English we say 'right-hand', 'rightmost' (if there are more than two), or 'on the right'. I have a feeling that in Am English it's OK to say 'the right chart'...:-?
