Verified step by step guidance

1. Understand that a supply curve shift to the right means an increase in supply at every price level, which is different from a movement along the supply curve caused by a price change.
2. Recall that an increase in the price of the good itself causes a movement along the supply curve, not a shift, so this does not shift the supply curve to the right.
3. Recognize that a decrease in the cost of production inputs lowers production costs, making it cheaper for producers to supply more at every price, which shifts the supply curve to the right.
4. Note that the imposition of a new tax on producers increases production costs, which shifts the supply curve to the left, not to the right.
5. Understand that a decrease in the number of sellers reduces market supply, shifting the supply curve to the left, so it does not cause a rightward shift.
