A clothing company is considering a new insulation for winter coats. To collect customer satisfaction data on the new insulation, the company is considering two methods. Method 1: The company offers the first 50 employees who volunteer to try out a coat with new insulation if they will report their satisfaction level after one month. At the end of the month, the 50 volunteers describe their satisfaction with the coat's performance.

Method 2: The company takes 50 volunteers and randomly assigns 25 of them to coats with the new insulation and the other 25 to coats with the current insulation. All volunteers wear the coats for a month and then describe their satisfaction with the coats’ performance.

Which method describes an experiment?

Method 2 is an experiment because both groups report their satisfaction with the coats.
Method 1 is an experiment because all volunteers receive coats with the new insulation.
Method 2 is an experiment because volunteers are assigned one of the two insulation types.
Method 1 is an experiment because the volunteers’ satisfaction with the new insulation can be measured.
