How do i change the animation's speed inside a blend tree from script

I want the Running_1 animation to be slow when the player jumps. So i want to change the animation’s speed from the script. Is there a way? This is in Base Layer > Locomotion.
Google assuming that i want to change the parameter (Speed) of the blend tree therefore providing me results based on that.
