Seedlings at the window

A class grew six seedlings, each with light from one direction, and measured how far each shoot bent after three days. A minus sign means a bend to the left, and a plus sign a bend to the right. One seedling, S3, had its tip covered with foil. You will find which seedlings bent towards their light, the average bend of the side-lit ones that did, and the ones that did not respond.

The idea. Light from the left should give a bend below $-10$ degrees. Light from the right should give a bend above $10$ degrees. Light from above should give a bend of $10$ degrees or less either way.

Your tasks.

1. Set towards to a list of True or False: did each seedling bend towards its light?
2. Set mean_side_bend to the average size of the bend, in degrees, of the side-lit seedlings that did bend towards the light.
3. Set no_response to the list of names of the seedlings that did not bend towards their light.
