Question

I have to draw some Supply/demand curves and I want to know if they are right

Personal computers: more user-friendly software become available and the costs of inputs are reduced.
Supply moves to the right, demand moves to the left, quantity goes up and so does price

Hospital services: higher wages paid to hospital employees accompanied by 4% increases in output per labor hour.
Supply moves to the right, demand does not move, quantity goes up and price goes down

Lift tickets for skiing: increased interest in skiing; higher costs for energy used by snow making machines (in a year with little snow temps in 20's F).
Supply does not move, demand moves to the right, quantity goes up and price goes up.

Supply moves to the left, demand moves to the left, quantity goes down and price cannot be determined

Supply moves to the left, demand moves to the left, quantity goes down and price cannot be determined
