Snow tires prices varies from brand to brand, ranging from 60 dollars to 200 dollars per tire. They are more expensive than regular tires. They do have more grips than regular tires, because they have a different rubber composition.
Snow tires!
Both Winter and Snow tires have a more aggressive tread pattern and are made of a softer rubber that grips better in cold weather. I believe that snow tires have a still more aggressive tread pattern than winter tires.
I don't believe anybody is required to use snow tires. In fact, some states recommend that you don't use snow tires unless the conditions are bad due to the fact that they can damage/wear the roadways.
Yes, that's a reasonable swap.
unfortunately the coeficient of friction between rubber tires and packed wet snow is so low that the inertia of the vehicle allows the vehicle to slip on the snow. Deeper snow or snow tires will increase the friction slightly and allow you to move in the direction of your choosing.
Snow tires!
Directional tires are ideal for hard surfaces in good weather conditions. The best tires for driving in snow are snow tires.

Snow tires cost slightly more than all weather tires. The actual cost of the snow tires would depend on the brand, style and size.
From what I know, they probably do not because snow tires have special pins build into it for gripping the snow/ice. It depends on the type of tire you are actually going to buy but generally mud tires are more expensive than snow tires.
if the studs are not installed they are just like regular snow tires
Michelin mud and snow tires get great traction, but if you want the best traction go with studded tires.
