What does the area corresponding to the critical value zcrt mean?
There is a graph that has a normal bell shape curve that has a vertical arrow that intersects the x axis far from the y axis. then everything to the left of the the vertical arrow is colored in blue. The question is asking what is that area? is it p or the area that corresponds to the critical value crt?
