dan.sleep:skewed left baby.sleep: No skew dan.grump:No skew

The first of the distributions is unimodal and is slightly skewed to the left. There is not much varience within this distribution.The second distribution is unimodal. It is not skewed and the varience is higher than the former data set.cor()The last of the histograms is bimodal,is not skewed, and has high varience within the distribution.

No. There does not seem to be any outliers.
