Histogram

#4
Hi,

To me, it looks like a right/positive skew but no a significant one, so you can treat it potentially symmetrical :)
But as Greta wrote not a normal but not very far from normal.

Why do you want to know if the distribution is normal? (say for what use)

You can check easily the skewness value and significance, and the Shapiro Wilk normality in the following link (for the raw data, not accumulated)
but I assume it won't give you much more than already wrote ...
