Classify each description as either an observational study or an experiment. A scientist seeks to test the ability of a new glove to retain heat. The glove is randomly placed on one hand of each participant, and an older model of the same product is placed on the other hand. A political scientist seeks to determine if women between the ages of 25 and 30 are more likely than men of the same age to vote for a Democratic candidate. The scientist selects a sample of voters from this age group to survey their political preference. Agricultural scientists seek to test the effects of a new pesticide on corn crops. Half of the participating farmers are assigned the new pesticide and the other half continue using an alternative pesticide. The crops are compared after two seasons. Random homeowners in a particular city are divided into two groups, those that currently use solar panels in their homes and those that do not. All participants are surveyed to determine whether electric bills are lower for those with solar panels.
