when the price of a jar of jelly decreased from $4 to $2, suppliers of jelly decreased production from 250,000 jars to 150,000 jars. What is the price elasticity of supply in this case? What is the interpretation of the estimated elasticity?

We can calculate elasticity with next formula:
Es= ((Q2−Q1)/(MidpointQ))/((P2−P1)/(MidpointP))
So, Es=((150,000-250,000)/(400,000))/((2-4)/(6)) = 0.75
As supply elasticity is less than 1, it means that supply is not price elastic. 1% change in price will lead to 0.75% change in supply.
