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 group of researchers randomly selects 4000 citizens of eight highly populated cities in the United States to study the health effects of pollution. The health of each subject is monitored over a five-year time span. 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.

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. To determine the effect of texting while driving, recent accident reports are collected. The reports are divided into a group of people who were texting at the time of the accident and a group of people who were not. A cancer study began by surveying male patients between the ages of 35 and 55 at a local hospital about their exercise routine. The health of these men is tracked over 10 years to determine the effect of exercise on lowering the risk of cancer. Researchers studying how exercise affects cholesterol sample 50 people who exercise regularly and 50 who do not. Blood was drawn from each person and serum cholesterol was measured.
